So far it was shown only in primates, rodents and perissodactyls [ 14151617 ]. Discussion 4. Bovidae The family Bovidae includes two major branches: Bovinae and Antilopinae [ 53 ]. Gladkikh O. Male sex chromosomes XY are non-homologous, while female sex chromosomes XX are homologous.
Autosomal genetic disorders occur due to either the non-disjunction in parent chromosomes Aneuploidy during gametogenesis or the Mendelian inheritance of deleterious alleles. Autosomes: Autosomes are labeled with numbers, from 1 to Cytogenetic data from about angiosperm species showed heteromorphic sex chromosomes in approximately half, mostly taking the form of XY sex-determination systems.
This is the key difference between autosomes and sex chromosomes. Non-sex chromosomes which determine the trait of an organism is identified as autosomes. Sex Chromosomes: A few of the chromosomes within a genome are sex chromosomes. Thank you for your feedback.
Overview and Key Difference 2. An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. The key difference between autosomes and sex chromosomes is that the autosomes contain genes that are responsible for the determination of somatic characteristics while the sex chromosomes contain genes that determine sex and sex-related characteristics of an organism.

Bos taurus. Also in the same subfamily, a translocation of an autosome to the X chromosome was reported in several Muntiacini species [ 7 , 49 , 50 , 51 , 52 ]. The order Cetartiodactyla exhibits great diversity of chromosome X morphology both within and between families.
