the process of both alleles being expressed independently is known as __________.
codominance
incomplete dominance
total dominance
partial dominance

Explanation:

Question 3

The locus of a gene is a fixed position on a chromosome. It does not change.

• Codominance: Both alleles are expressed independently. For example, in the ABO blood - group system, if an individual has the \(I^A\) and \(I^B\) alleles, both are expressed, resulting in the AB blood type.
• Incomplete dominance: The heterozygous phenotype is intermediate between the two homozygous phenotypes. For example, in snapdragons, a red - flowered plant (\(RR\)) and a white - flowered plant (\(rr\)) produce pink - flowered (\(Rr\)) offspring.
• Total dominance: One allele completely masks the expression of the other allele. For example, in pea plants, the allele for tall (\(T\)) is dominant over the allele for short (\(t\)).
• Partial dominance is not a standard genetic term in the context of allele expression like the others.

False
