Question

Red hair (b) is recessive to brown hair (B). Which of the following explains

how two brown haired parents can produce a red haired child? *

Answer 1

In order for two brown-haired parents to produce a red-haired child, both parents must carry the recessive red hair allele (b) in their genetic makeup. When they have a child, there is a possibility that both parents will pass on the recessive red hair allele to the child, resulting in the child having red hair.

In order for two brown-haired parents to produce a red-haired child, both parents must carry the recessive red hair allele (b) in their genetic makeup.

When they have a child, there is a possibility that both parents will pass on the recessive red hair allele to the child, resulting in the child having red hair.

To illustrate this, let's use a Punnett square. Let's represent the brown hair allele as B and the red hair allele as b.

When two heterozygous parents with the genotype Bb mate, they each have a 50% chance of passing on either the B or b allele to their child.

So, in 25% of the offspring, both parents pass on the b allele, resulting in the child having red hair.

Answer 2

Yes, the two brown-haired parents can produce a red-haired child

Step-by-step explanation:

• According to the theory, the gene pair can have two combinations either red pair or the non-red pair the allele for the red hair is always recessive.
• The parent's genes with the combination of two brown-haired genes will produce red hair color. And the red hair color has lots of health issues.
• Due to the recessive character, the child can have red hair.
