Answer:
Doctors may try to stimulate spermatogenesis by prescribing the person, an estrogen receptor blocker, which leads to the stimulation of the hypothalamus and pituitary gland in the brain. This stimulation results in the generation of FSH and LH hormone production.
They release both hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The production of these hormones will start the production of the sperm
Facial hairs are related to the specific hormones during puberty, Androgens are male sex hormones, including testosterone. These hormones are related to the production of sperm, masculinity, and facial hair.
Answer:
A) The eye colour may be controlled by one or more genes, mutation lies in two different genes and has complemented each other.
B) Parent 1: w1w1 w2+w2+ Parent 2:w1+ w1+w2w2
Gametes: w1 w2+ and w1+w2
Offspring genotype: w1 w2+ w1+ w2
Explanation:
This condition may be because of complementary genes. When the presence of two or more genes are required for a particular trait and the absent of one of the genes affects the character, it is referred to as complementary genes. In this condition the wild type of fly have AA/BB type of gene and expression of both gene is responsible for red coloured eyes.
a. Mutation in any of the genes, affect the accumulation of red pigment in eyes and cause the eyes to be white colored. Given that two mutants W1 and W2 have white eyes but both have mutation in different genes. Suppose W1 has mutation in AA gene(genotype aaBB )and mutant W2 has mutation in BB gene (genotype AAbb).
b. Crossing between mutants give red colour eyes fly:
Parents AAbb x aaBB
Gametes Ab aB
Progeny AaBb
That is,
Parent 1: w1w1 w2+w2+ Parent 2:w1+ w1+w2w2
Gametes: w1 w2+ and w1+w2
Offspring genotype: w1 w2+ w1+ w2
Result: progeny of mutant have both type of functional alleles (A and B), responsible for red colour of eyes. Thus the progeny will be with red colour eyes.
Answer:
C
Explanation:
C no is the answer I think so. but not sure
