Recombination of chromosomes may lead to heterogamety before the development of sex chromosomes, or recombination may be reduced after sex chromosomes develop. Developmental milestones: E. These are known as the gross motor skills and depend on muscle strength and tone. For a mammal to be female, the individual must receive an X chromosome from both parents, whereas to be male, the individual must receive a X chromosome from their mother and a Y chromosome from their father.

The Sox9 triggers the development of non-sexed definition of sex cell chromosomes in Stourbridge into testes instead of ovaries. Both food and air pass through the pharynx on the way to the lungs or stomach.

Human sex cells contain one complete set of 23 chromosomes. The midpiece region contains several mitochondria which provide the energy for the motile cell.
