Current Biology. Male sterility likely arises first as an adaptation to prevent selfing. This is useful for identifying some human disorders. This process is the most clear-cut form of sex determination. Sex Chromosomes.

The X chromosome, being larger, carries many more genes than does the Y. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y.

Sex Chromosomes X-O. The move from a monoecious to dioecious system requires both male and female sterility mutations to be present in the population. The female gamete, called the ovum, is nonmotile and relatively large in comparison to the male gamete.

These are also known as gonosomes. Redirected from Sex chromosomes. Some males are born as XXY, and they may show some female physiological characteristics. They produce sperm cells that contain either an X chromosome or no sex chromosome, which is designated as O.

Finally, to assess whether TBT-dependent changes in F3 and F4 sperm chromatin accessibility related with the metabolic phenotype observed in F4 animals, we functionally characterized genes spanned by DAIs in F3 and F4 sperm. TBT with 6 biological replicates for each.

The overall extent to which isoDMBs, annotated genes or isochores overlap was measured using the Jaccard index, which is calculated by dividing the total number of base pairs where isoDMBs overlap with either annotated genes or isochores by the total number of base pairs spanning isoDMBs or annotated genes, or isoDMBs or isochores.
