This question has two parts.

In cattle, the hornless trait is dominant to the horned trait. A farmer starts with a herd of cattle heterozygous for the horned trait and wants to keep the herd hornless. To keep the hornless trait, the farmer builds fences around the farm to prevent the cattle from mating with any horned cattle in the area.

Nødvendig

1

Which statement best describes what will MOST LIKELY happen to the cattle population on the farm over time?

There will continue to be some horned cattle in each generation.

All of the cattle will remain hornless.

The next generation of cattle will all be horned.

Horned cattle will appear after every two generations.

Nødvendig

1

Which evidence supports your answer for Part A?

Two recessive alleles could be inherited to produce horned cattle.

The appearance of dominant and recessive alleles switches periodically.

The hornless allele is dominant, and the chance of it appearing is always 100%.

The recessive allele will become a dominant allele after the first mating.

Nødvendig
