Sex chromosomes, sex determination, and sex-linked sequences in Microtidae.
The Arvicolidae is a widely distributed rodent group with several interesting characteristics in their sex chromosomes. Here, we summarize the actual knowledge of some of these characteristics. This mammalian group has species with abnormal sex determination systems. In fact, some species present the same karyotype in both males and females, with total absence of a Y chromosome, and hence of SR...
متن کاملPhenotypic and Genetic Analysis of Lori-Bakhtiari Lamb's Longevity Up to Yearling Age for Autosomal and Sex-Linked Chromosomes
The data set used in this study contained 8793 records of lamb's longevity (days) from 320 sires and 2349 dams collected during 1989 to 2014, from the Lori-Bakhtiari flock at Shooli station in Shahrekord, Iran. Genetic parameters (partitioned into autosomal, sex-linked and maternal) and breeding values of cumulative lamb's longevity from birth up to yearling age (at 1, 2, 3, 6, 9 and 12 months)...
متن کاملSex from W to Z: evolution of vertebrate sex chromosomes and sex determining genes.
Sex determination in major vertebrate groups appears to be very variable, including systems of male heterogamety, female heterogamety and a variety of genetic and environmental sex determining systems. Yet comparative studies of sex chromosomes and sex determining genes now suggest that these differences are more apparent than real. The sex chromosomes of even widely divergent groups now appear...

متن کاملSex-Linked period Genes in the Silkmoth, Antheraea pernyi Implications for Circadian Clock Regulation and the Evolution of Sex Chromosomes
Regulation of the period (per) gene is a critical feature of circadian clock function in insects. Here, we show that per is sex-linked in the silkmoth, Antheraea per-nyi. The previously described silkmoth per gene is found on the Z chromosome. Silkmoth per is not dosage compensated at either the RNA or the protein level. Although earlier studies showed the presence of an oscillating endogenous ...
