Question

In rabbits, white fur is recessive while brown fur is dominant.

Explain how a rabbit could be born and have white fur (only recessive) even though both parents have brown fur? Hint: Both parents are heterozygous. In your explanation, describe 1) how dominant and recessive alleles affect each other, 2) what it means to be heterozygous, and 3) how this leads to the offspring with white fur (recessive only).

Answer 1

There is always a chance to get a recessive gene on a child

[Use the Punnett Square]
- You were told that the parents are heterozygous (1 dominant and 1 recessive)
- I used `F` for the dominant brown fur and `f` for the recessive white fur


When both parents are heterozygous for the same gene, theres always a 25% chance of obtaining the recessive gene (of course compared to the 75% of the dominant, which is mostly the case)
