dominant-recessive inheritance
B

E
incomplete dominance
Verified step by step guidance1
Understand that traits with continuous phenotypic variation, such as height or skin color, do not fall into discrete categories but rather show a range of possibilities.
Recognize that dominant-recessive inheritance typically results in discrete phenotypic categories, not continuous variation.
Consider sex-linked inheritance, which involves genes located on sex chromosomes, often resulting in distinct phenotypic differences between sexes rather than continuous variation.
Evaluate multiple-allele inheritance, where more than two alleles exist for a gene, but this does not necessarily lead to continuous variation.
Identify polygene inheritance as the form where multiple genes contribute to a single trait, resulting in continuous phenotypic variation due to the additive effects of many genes.
