In a matting between two individuals wha are heterozygous for a trait, what is the probability the offspring will express the trait recessive? What percent?

1/4 or 25% chance of expressing recessive genes

Explanation:

Punnett Square ( Dominant B, recessive b)

~ B | b

B | BB | Bb

b | Bb | bb

1/4 or 25% chance of hom0zygous dominant (hom0zygous dominant)

1/2 or 75% chance of expressing dominant gene (heterozygous with recessive gene hidden)

1/4 or 25% chance of expressive recessive gene (hom0zygous recessive)

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

the answer is c because it is most logical.
