b. male, XY
c. male, XX
d. male, it depends on what genetic information the oocyte carries
e. female, XX

Answer 1

e. female, XX

Step-by-step explanation:

In humans, females are homogametic because they produce only one type of gametes. All the female gametes ( oocyte or ova) have X-sex chromosome. Whereas, human males are heterogametic. they produce two types of gametes. Half of the gametes (sperms) have X-sex chromosome and half of the gametes (sperms) have Y-sex chromosome.

Therefore, an oocyte or female gamete is fertilized by an X-bearing sperm, the child will be born a female with the chromosomal pair of XX. one X from the male and one X from the female.
