Human which has XY chromosomes is a
The correct option is A Male
Human follows XX- XY mechanism of sex determination. Human females have forty-six chromosomes arranged in twenty-two homologous and homomorphic autosomes and two copies of X chromosomes as sex chromosomes (44+XX). Males have twenty-two homomorphic pairs and one heteromorphic pair, the XY pair (44+XY). The Y-chromosome carries Y gene that is responsible for the development of testis in human males; absence of this gene in females determines feminism. Thus, sex determination in human is predictable. Thus, the correct answer is option A.
