Exploring human sex chromosomes, sex determination and sex reversal using bioinformatics approaches Lesson. Honts, J E. Eisen, E.
It has been proposed that oocytes in the XO ovary escape the checkpoint mechanism by the ability of the univalent X-chromosome to form a non-homologous association with itself or with an autosome Speed Abstract In the XY pachytene spermatocyte, the sex chromosomes do not synapse except for the pseudoautosomal region and become transcriptionally silenced.
Genes that are carried by either sex chromosome are said to be sex linked. Indeed, C. This gene is called the SRY gene. In this context, we studied chromosomes, which are found in the nucleus and contain the hereditary material.
Abnormalities in the chromosomes autosomes or sex chromosomes results in the retardation in growth of an organism or delay in development.
A similar distribution was observed in the two genotypes of ovaries at three developmental stages examined. Hoey, and K. Since usually men inherit Y chromosomes, they are the only ones to inherit Y-linked traits.
