Qualitative and quantitative data obtained from lines of chickens divergently selected for male mating ability and from the unselected randombred control population were used to evaluate the relationship of comb type alleles and mating behavior. An apparent antagonistic relationship was found between the rose (R) allele and low cumulative number of completed matings in the low mating line, while the opposite association was found for the pea (P) allele. No association was found between alleles of the rose and pea loci and mating ability in the high mating or control lines. An antagonistic relationship was indicated between the rough (He+) allele and a high cumulative number of matings. These results support the hypothesis that two genetical systems interact to influence the mating frequency of male chickens and further suggest that alleles of the rose, rough, and pea loci should not be used as marker genes to estimate genetic drift in random mating populations maintained by natural matings.

Semiotics, as a study about a sign as part of social life, leans on the rule or social code in a society. A rose for Emily is a short story tells about the detail of the story that has in Emily’s life and an odd relationship with her father, her boy friend, Jefferson City, and her terrible secret that she was hiding. The objective of the article was to describe symbols used in the short story. The data was analyzed by using semiotics approach. It was found that there are some symbols in the short story illustrated by the author. They are “The Rose, The Move of her Hair, Ticking of Watch, The House and Black Color”. The Rose was symbolized as the relationship of Emily and her father. Emily grew up in luxurious. And The move of her hair was as a symbol of changing of her life. Moreover, ticking of watch was as a symbol to come to the new generation. Both of the House and Emily have changed after the death. Her house extinct as abandoned. Lastly, the black color was a symbol of death, depression, and darkness. The writer found that each symbols in A Rose for Emily illustrated the darkness and mysterious life of Miss Emily. Each of the symbols helps the author to create the story.

The conclusion by Suit, Matney, Doudney & Billen (1964) that Hfr donor cells ofEscherichia coliK12, starved of required amino acids can mate, has been re-examined. It appears that their conclusion is not valid and that apparent fertility of amino-acid starved cells is due to cross-feeding by the F−cells. The relationship of this result to the alternative mechanisms for chromosome transfer inE. coliis discussed.

This chapter focuses on works by Corey Field. Field has added two songs to his earlier Escape at Bedtime to form a nicely balanced trio of lullabies. Each movement is neatly constructed, and shows considerable flair and sensitivity to the relationship of voice and piano. The first poem also comes from Robert Louis Stevensons’s A Child’s Garden of Verses (1885), but the third sets a W. B. Yeats text (from The Rose, 1893). The cycle is relatively undemanding vocally and has an attractive immediacy. It will suit either a tenor or soprano, giving them a chance to shine vocally, while the piano’s luminous contribution gives strong rhythmic support. The style is a fresh, accessible mix of tonality and light chromaticism, with strophic verses treated conventionally but never rigidly. Each song has its own distinctive character. The simpler outer songs frame a middle movement that is a little more ambitious, and the work begins and ends with piano solos.

Fleeced: Derrida and ‘the Deciding Discourse of Castration’

This chapter explores the relationship of deconstruction to psychoanalysis, and reads the Genet column of Glas in terms of the deconstructibility of ‘the deciding discourse of castration’, as Derrida puts it. The fleece that Genet imagines Harcamone wearing in The Miracle of the Rose takes centre stage, as much as Genet’s flowers. The fleece is both garb and pelt, at once a talismanic scalp, a part that has been brutally cut away, and a covering used to shield or shelter what is vulnerable or exposed. It is both something stolen, and a protective barrier against loss. To get ‘fleeced’ already carries a double and ambiguous set of possible meanings, then, and Derrida puts it to work in the interests of a double-sexed deconstruction of castratability. If the erection cannot ‘fall’ without re-elevating the entire edifice or column of that phallogocentrism of which castration would paradoxically form an uncastratable part, Derrida’s insertion of a deconstructive ‘hole in erection’ exposes to a powerfully deciphering reading this tale of castration’s uncastratability. The chapter reads into the Hegel column of Glas precisely this deconstructibility of a ‘deciding discourse of castration’, notably in terms of the Hegelian interpretation of Antigone’s politics.

ABSTRACTIn total, 245Cryptosporidium parvumspecimens obtained from calves in 205 Irish herds between 2003 and 2005 were subtyped by sequencing the glycoprotein genegp60and performing multilocus analysis of seven markers. The transmission dynamics ofC. parvumand the influence of temporal, spatial, parasitic, and host-related factors on the parasite (sub)populations were studied. The relationship of those factors to the risk of cryptosporidiosis was also investigated using results from 1,368 fecal specimens submitted to the veterinary laboratories for routine diagnosis during 2005. The prevalence was greatest in the northwest and midwest of the country and on farms that bought in calves. The panmixia (random mating) detected in theC. parvumpopulation may relate to its high prevalence, the cattle density, and the frequent movement of cattle. However, local variations in these factors were reflected in theC. parvumsubpopulations. This study demonstrated the importance of biosecurity in the control of bovine cryptosporidiosis (e.g., isolation and testing of calves before introduction into a herd). Furthermore, the zoonotic risk ofC. parvumwas confirmed, as most specimens possessed GP60 and MS1 subtypes previously described in humans.

Economic Use

Currently, marker genes are often used in dairy cattle breeding. Scientists are studying the relationship of gene polymorphism with such economically useful traits as milk productivity, productive longevity, growth, development, etc. The short period of the economic use of cows and the late intake of live weight necessary for insemination cause economic losses to agricultural organizations. The goal of the research was to study the relationship of the polymorphism of the somatotropin gene with live weight during the first insemination and productive longevity of cows. The study was conducted in the Sverdlovsk region on cattle of Holstein Black-Motley breed in 2018–2019. Two samples were formed: heifers and retired cows genotyped by the somatotropin gene. In animals, LV-somatotropin gene polymorphism was determined. The determination of polymorphism included the following steps: DNA isolation, polymerase chain reaction (PCR), restriction enzyme production, restriction products run on an agarose gel, visualization using a transilluminator. The research results were processed using IBM SPSS Statistics 23 software,and the reliability criterion was analyzed. LV-polymorphism is represented by three genotypes: LL,LV and VV. The authors studied the frequency of genotypes in the population of holsteinized cattle. It was revealed that the LL genotype is widely represented in the population – 77.2%, animals with the LV genotype are found more rarely – 22.2%. The VV genotype is extremely rare in the population – 0.6%. It was also revealed that the L allele is a common population allele – 88.3%. In the course of studying the relationship of LV polymorphism with live weight during the first insemination, it was found that animals with the LL genotype grow faster and reach the live weight necessary for fruitful insemination earlier. At the same age, heifers with the LV genotype had a mass of 400 kg, with those with the LL genotype – 9 kg more at p ≤ 0.01. When studying the effect of somatotropin gene genotypes on productive longevity, it was found that cows with the LV genotype have a longer economic use. The difference with peers with the LL genotype was 0.5 lactations at p ≤ 0.05. As a result of the studies, it can be concluded that the LL and LV genotypes are the desired option for the holsteinized cattle population. The LL genotype is associated with growth and development, and LV – with productive longevity.
