Distinguish between sex chromosomes and autosomes in humans in Jackson
Initial genome-wide association studies GWAS neglected sex chromosome data in their analyses: the sexually dimorphic expressed quantitative trait loci eQTLs they identified associated with polygenic traits such as waist—hip ratio 1, and bone density []were autosomal [].

Therefore, AEs and CAs should be considered as different structures, and more significantly, they could be regulated in different ways since both structures are able to follow a different pattern of development on the sex chromosomes during first meiotic prophase.

Each autosome contains a large number of genes arranges in a definite sequence. There is a total of 46 chromosomes in the human genome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.
Thus, sex chromosomes are of 2 types; X and Y.
- Many animals, including humans have two types of chromosomes: Autosomes and sex chromosomes.
- The chromosomes, apart from the sex chromosomes , are known as autosomes of an organism. The number of chromosomes varies from one organism to others.
- 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.

Trisomy 2 mosaicism with caudal dysgenesis, Hirschsprung disease, and micro-anophthalmia. The formation of a chiasma in the PAR holds sex chromosomes associated until they segregate at anaphase I. We used a previously published 10,rad rhesus macaque radiation hybrid panel 52 , and a set of new 25,rad radiation hybrid panels from marmoset, mouse, bull, and opossum, constructed by William J.
Y-linked genes filled circles and pseuodgenes open circles listed in order of position of human X chromosome homolog. Novel mutations target distinct subgroups of medulloblastoma. Although traditionally attributed to gonadal sex hormone effects, recent work has begun to shed more light on the contribution of genetics — and in particular the sex chromosomes — to these sexual dimorphisms.
