Wally has just been told that he has an enlargement of the walnut-sized gland at the base of his urethra. this gland is called the:

Prostate gland

The prostate gland is a small walnut sized gland that encircles the first part of the urethra which moves urine from the bladder along the penis. A thick white fluid is produced by the prostate and this fluid combines with the sperm from the testicles to form semen. The semen is turned into liquid by a protein called prostate-specific antigen (PSA) which is produced by the prostrate.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
