Heredity And Genetics E


What is an example of a trait in an organism that shows an intermediate phenotype , an incomplete dominance?

What is an example a trait that has multiple alleles?

Dominance in genetics is a relationship between alleles of a gene, in which the phenotypic effect of one allele masks the phenotypic effect (phenotype) of another allele at the same locus.[1] In the simplest case, where a gene exists in two allelic versions (designated A and B), three combinations of alleles (genotypes) are possible: AA, AB, and BB. If AA and BB individuals (homozygotes) show different variations of the trait (phenotype), and AB individuals (heterozygotes) show the same phenotype as AA individuals, then allele A is said to dominate or be dominant to or show dominance to allele B, and B is said to be recessive to A. If instead AB has the same phenotype as BB, B is said to be dominant to A. Dominant/recessive allele pairs have been widely used in classical genetic analysis, but naturally occurring alleles commonly show more subtle and complex relationships.

Blue eyes is an incomplete dominance.

And also weight can be an incomplete dominance.

Brown eyes is one of the complete dominance

Brown, Blue eyes and weight can be an incomplete dominance.

Incomplete dominance is seen in cross-pollination experiments between red and white snapdragon plants. The dominant allele that produces the red color is not completely expressed over the recessive allele that produces the white color. The resulting offspring are pink.

Brown hair is a dominance.
