3. Extensions to Mendelian Inheritance

Forms of inheritance that are determined by more than two alleles are referred to as:

Which of the following best explains why the relationship between genes and traits is often complicated in humans, particularly in the context of variations of dominance?

Traits can be dominant, which means they can be seen and are capable of masking a different trait. Which term best describes such traits?

Which genetic phenomenon is described when one gene has several different forms, resulting in more than two phenotypes?

Which term describes a genotype that contains two different alleles at a given locus?

A diploid individual carrying two different alleles at a given gene locus is called:

A trait that exhibits continuous variation (such as human height) is called a(n) ______ trait.

Which definition best describes polygenic traits?

If the phenotype reflects the activities of more than one gene, it is called a ______ trait.

A situation where a single individual expresses two different alleles is referred to as:

A heterozygous genotype codes for a blending of phenotypes in which type of inheritance?

Which of the following best describes dominant alleles in the context of genetic inheritance?

Which term best describes the situation when an allele has no noticeable effect on an organism's phenotype?

Which type of allele is sometimes referred to as a loss-of-function gene?

The gene for dark eyes is ___ over the gene for blue eyes, which is recessive.
