Question

Explain why an organism with a homozygous dominant genotype has the same phenotype as an organism with a heterozygous genotype. Thank you for your help!

Answer 1

Let's say that the dominant trait is tall (T) and the recessive trait is short (t). Your genotypes would be TT and Tt. The phenotypes would both be tall b/c tall is the dominant trait and short is recessive. That's about the best I can explain it.

Hope this helps. :)

Answer 2

The dominant allele shows whether the organism has one copy of the dominant or two. The recessive allele only shows when it is the only kind of allele.
