Which of the following statements about sex determination in humans is...
Sex Determination in Humans
Sex determination in humans is a complex process that is influenced by genetic factors.
The Presence of the Y Chromosome Determines Maleness
In humans, the presence of the Y chromosome determines maleness. Males typically have one X and one Y chromosome, while females have two X chromosomes. The Y chromosome carries the SRY gene, which is responsible for the development of male characteristics. This gene triggers the development of the testes, which produce hormones that result in the development of male reproductive organs.
Genetic Basis of Sex Determination
The combination of sex chromosomes inherited from the parents determines the sex of an individual. If an individual inherits an X chromosome from both parents (XX), they will develop as female. If they inherit an X chromosome from the mother and a Y chromosome from the father (XY), they will develop as male.
Environmental Factors
While environmental factors can influence certain aspects of sexual development, such as the expression of secondary sexual characteristics, the primary determinant of sex in humans is the presence of the Y chromosome. Environmental factors alone cannot change the genetic basis of sex determination.
