A heterozygote possesses a phenotype that is intermediate between the homozygous dominant and homozygous recessive phenotypes. This is most likely an example of ________.
A) lethal alleles
B) incomplete dominance
C) gene dosage
D) sex-influenced inheritance

Question

Quizplus · Accepted Answer

In incomplete dominance, the heterozygote shows a blended or intermediate phenotype between the two homozygous phenotypes. This is in contrast to complete dominance where the dominant phenotype is fully expressed and recessive phenotype is masked, and codominance where both dominant and recessive phenotypes are expressed equally. Lethal alleles cause death in the organism, gene dosage refers to the effect of the number of copies of a gene, and sex-influenced inheritance refers to the influence of sex hormones on the expression of certain genes.
