Question

Assume navy blue is dominant over yellow for fur color of the mythical jackalope. Which of the following is true if two heterozygous individuals mate? a) All offspring will have navy blue fur. b) All offspring will have yellow fur. c) Offspring have a 25% chance of having yellow fur. d) Offspring have a 75% chance of having navy blue fur.

Answer 1

If two heterozygous individuals mate, the offspring have a 25% chance of having yellow fur and a 75% chance of having navy blue fur. This is due to the ways in which genetic traits can combine in the offspring.

Step-by-step explanation:

The question pertains to the inheritance of fur color in the mythical jackalope, where navy blue is dominant over yellow, and if two heterozygous individuals (carriers of both navy blue and yellow) breed. The answer to people's question is both c) Offspring have a 25% chance of having yellow fur and d) Offspring have a 75% chance of having navy blue fur.

This form of Mendelian inheritance can be explained via Punnet square, which shows that there is a 25% chance for the offspring to be yellow (yy), a 50% chance to be heterozygous navy blue (Yy), and a 25% chance to be homozygous navy blue (YY). Thus, adding the likelihoods of navy blue (50% heterozygous navy blue + 25% homozygous navy blue), shows a total of 75% chance for the offspring to have navy blue fur.
