Agouti is a type of coat-color pattern in mice that cannot be expressed in albinos (white mice). Non Albino mice without the dominant agouti allele ( AAbb and Aabb) are black. An agouti mouse that is heterozygous at the albino ( A) and agouti ( B) loci ( AaBb) is mated to an albino mouse that is heterozygous at the agouti locus ( aaBb). What percent of the progeny are likely to be agouti

37.5%

Explanation:

These here are

Black (AA or Aa) and albino (aa)

Agouti (Bb or BB)

Thus, a cross between

AaBb and aaBb

The percent of the progeny which are likely to be agouti would be

A. a. B. b

a. Aa. aa. B. BB. Bb

a. Aa. aa. b. Bb. bb

The probability of agouti would be

1/2 (Aa) * 3/4 (BB or Bb)

= 3/8

= 37.5%

answer: c

explanation:

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
