Question

In humans, having freckles is dominant over not having freckles. Neither Maya nor her husband Rich has freckles. What is the probability that their daughter will have freckles? 100% 75% 25% 0%

Answer 1

The answer is 0% because both of his parents have recessive genes to not having freckles therefore she cant have freckles.

Answer 2

Answer:

0%

Explanation:

Freckles are the famous brown spots on the skin, which appear especially in people with fair skin.

Freckles are characteristics determined by dominant alleles, that is, they are only expressed in homozygous dominant (AA) or heterozygous (Aa) people. However, homozygous recessive people (aa) do not have any freckles.

For this reason, two people who do not have freckles have the genotype "aa", if these people have a child, the child will also have the genotype "aa" and will not have freckles. Therefore, two people without freckles have a 0% probability of having a child with freckles.
