Question

11. In pepper plants, the allele for hot flavor (H) is dominant to the allele for

mild flavor (h). A farmer crosses a homozygous dominant plant with a
recessive (mild) plant. What percentage of the offspring from this cross will
have hot flavor?
25%
50%
75%
100%

Answer 1

100%

Step-by-step explanation:

When a homozygous dominant plant (HH) is crossed with a recessive (mild) plant (hh), the offspring will all be heterozygous (Hh) and have the dominant hot flavor allele.

The Punnett square for this cross would be:

| | H | H |

|---|---|---|

| h | Hh | Hh |

| h | Hh | Hh |

As we can see, all of the offspring (100%) will have the dominant H allele and therefore have hot flavor.

Therefore, the correct answer is 100%.
