Answer 1

Answer: Remember there are 46 chromosomes in a (normal) human nucleus, which consists of 23 pairs of chromosomes.

Of these, one pair are the sex chromosomes.

In females, the sex chromosomes are XX

In males, the sex chromosomes are XY

So the karyotype of a human male would consist of 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.

Answer 2

Answer:

The correct answer is

C. 22 pairs of autosomal chromosomes, 1 X chromosomes, and 1 Y chromosomes

What occurs differently if the egg is fertilized during ovulation

Answers

If the egg is fertilized during ovulation, the fusion of the sperm and the egg forms a pronuclei then into a zygote (wherein the nuclei is already one or fused completely). It will then undergo the cleavage stage wherein the egg becomes a 2-celled to a 4-celled and to an 8-celled egg. Next is the morula stage as the cells grow larger in number. After that, the embryo starts to rise - the blastocyst stage. Last is the implanted blastocyst stage; the egg is now attached to the uterine lining.
