Two diverse species<span> naturally breed an offspring, and selective pressures favor </span>new<span> traits in a given environment, (they evolve). hope this helps</span>
Archaea do still exist but only in extreme environments. Pointing to this is the fact that they were undiscovered for a while until they were eventually found in aquatic environments with extremely high temperatures.
Dominant epistasis happens when thedominant allele of one gene masks the expression of all alleles of another gene. If an organism inherits one or two copies of the dominant allele, they will have the trait. ... Heterozygous means that two different alleles for a trait are inherited instead of two of the same allele.
I hope this helps :)
