Question

In humans, normal skin color is dominant over albino color. Make a cross of the expected result if a hybrid Aa and albino aa produce offspring. How many children out of four are expected to be albinos?

Answer 1

IN HUMANS, NORMAL SKIN COLOUR IS DOMINANT OVER ALBINO COLOUR.

Step-by-step explanation:

If a hybrid Aa and albino aa produce offspring, we can determine the expected results by using Punnett square analysis.

When crossed, the genotype of the hybrid parent Aa can produce two possible genotypes: AA and aa. Since normal skin color is dominant (A), and albino color is recessive (a), the offspring will have a 50% chance of inheriting the dominant allele (A) and a 50% chance of inheriting the recessive allele (a).

By creating a Punnett square, we can determine the possible genotypes and phenotypes of the offspring:

A a

-----------------------------

a | Aa aa

Since there is one aa genotype (albino) out of the two possible genotypes, 1 out of 4 offspring is expected to be an albino.
