Question

what is the role of father in sex determination ​

Answer 1

Answer:

In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans.

Answer 2

Answer:

Father's sperm participate in the sex determination. Sperm contain both x an y chromosome, when x chromosome fuse with ovum from mother then it form girl baby but when it fuse with y chromosome of father then form boy baby.
