Question

There are two types of pea plants: those that produce round seeds and those that produce wrinkled seeds. A single gene controls which type of seed a pea plant will produce.

An experiment shows that pea plants containing an allele for round seeds will always produce round seeds.

Based on this information, we can conclude that the allele for round seeds in pea plants is _______.

Answer 1

We can conclude it is dominant since it says that it will "always" produce the round seeds. Dominance always has a great impact of one of the genes. In this example that greater gene is the round seeds in the pea plants.

Let me know if you need to know anything else. :)
