Question

For a pea plant that is true breeding for a particular trait how many different alleles are present at the locus in question?

Answer 1

The other answerer was correct that there would only be one kind of allele that would be present in a true breed. This is due to the fact that the trait in question is homozygous (same allele).

Hope this helps...

Answer 2

Bred true means it is homozygous, and thus, only 1 allele.
