Triploids have three sets of chromosomes per cell tri- means three. The presenting part determines the presentation.

The diploid chromosomes are pulled apart into two daughter cells, each containing a single set of chromosomes a haploid state. Each cell has an exact and identical copy of DNA with a full set of chromosomes. This atlas allows them to examine mRNA, the genetic material used to make proteins, in any single testicular cell.

Thus, we get our male and female cells. Approximately 5% of the human genome resides on these chromosomes -- 1, genes on the X and on the Y. This means that. Mutations in genes involved in the primary sex determination decision in the supporting cell lineage such as SRY, SOX9 and WNT4 may lead to XX germ cells differentiating as male or XY germ cells differentiating as female as a consequence of somatic sex-reversal in the gonad (Fleming and Vilain, ). Such sex-reversed patients are typically Cited by:
