a gene with two dominant alleles that expressed at the same time is-
a) codominant
b) mutational
c) incompletely dominant
d) polygenic
I know its not c
I believe that it is A
To determine the correct answer, let's break down the options and analyze them one by one:
a) Codominant: In codominance, both alleles are expressed simultaneously and equally in the phenotype of an individual. This means that neither allele is fully dominant or recessive over the other. Individuals with codominant alleles will display traits that show characteristics of both alleles.
b) Mutational: The term "mutational" refers to a change or alteration in the DNA sequence. It is not directly related to the expression of two alleles at the same time.
c) Incompletely dominant: In incomplete dominance, a heterozygous individual displays an intermediate phenotype that is a blend of the two homozygous phenotypes. This means that one allele is not completely dominant over the other, resulting in a unique phenotype.
d) Polygenic: Polygenic inheritance refers to the inheritance of traits that are determined by the combined effects of multiple genes. This term is not relevant to the situation described in the question.
Given the options provided, the correct answer is a) Codominant. When a gene has two dominant alleles that are expressed at the same time, it indicates codominance.
