Statistical tests of neutrality of mutations. Ellegren H, Parsch J. Suzuki R, Shimodaira H. Key Differences Between Autosomes and Sex Chromosomes Given below are the critical points to understand the difference between the autosomes and sex chromosomes: The pair of chromosomes that regulate the somatic characters of the body are known as autosomeswhereas the pair of chromosomes that determines the sex of an organism, as they regulate the sex-linked traits are known as sex chromosomes or allosomes.
Phil Trans R Soc B. Mamm Genome.
Presence of target sequences on clones was confirmed by amplification of loci using PCR and sequencing using original primers. Z- and W-specific loci were likely, at one time, pseudoautosomal. We conclude that, if any difference in population genetics distinguishes the PAR from autosomes, it is that the PAR is characterized by slightly higher rates of recombination and slightly lower LD than autosomal loci and that both genomic compartments appear to depart from a standard neutral model of a single population, as measured by the multilocus HKA test.
Convergent recombination suppression suggests role of sexual selection in guppy sex chromosome formation.
Sex-chromosome recombination in common frogs brings water to the fountain-of-youth. PDF kb. Dmrt1 polymorphism covaries with sex-determination patterns in Rana temporaria. Similarly, girls who are missing a sex chromosome have a specific syndrome Turner syndrome , whereas fetuses who are missing a nonsex chromosome do not survive.
