Question

A dig breeder discovers two of her puppies have abnormal genitalia. Chromosomal tests (cytogenetic analyses ) indicate that the male dog's karyotype lacks a Y chromosome, but instead has an XX chromosome pair, with one of the X-chromosome slightly larger than usual. Whereas, the female dog's karyotype reveals an XY chromosome pair, with Y-chromosome being slightly shorter than normal (being mammals, male dogs are normally XY and females are XX).

b) Suppose you discover a female dog with normal-sized XY chromosome pair, why this female is not a male?

Explanation / Answer
