What is and example of in complete dominance?

Answer 1

Complete dominance is when the presence of one allele ensures that the trait of the other allele is not displayed.

For example, if B codes for black fur and b codes for white fur, a rabbit with Bb will have black fur. This is because the B shows complete dominance over the b - meaning that black fur will result.

If this was incomplete dominance, a rabbit with Bb would have a mix - so grey fur.

If it was codominance, a rabbit with Bb would have black and white patches, dots or splotches.

Answer 2

Complete dominance is when the F1 offspring look like one of the two parents. Incomplete dominance is when neither allele for a gene is completely dominant over the other which leads to a phenotype (physical look or characteristic) somewhere between the two parents. An example of complete dominance would be in Mendel's classic pea cross experiment, with yellow peas being dominant to green peas. More peas would be yellow than green. An example of incomplete dominance would be with snapdragons. If a red true breeding snapdragon were crossed with a white true breeding snapdragon, the F1 generation offspring would all be pink, because neither the 'red' allele nor the 'white' allele was completely dominant over the other leading to a hybridization in color somewhere between the two parents.

Answer 3

An example of incomplete dominance is when a red flower and a white flower cross-pollinate to produce pink offspring. In this case, neither the red nor the white allele is dominant over the other, resulting in an intermediate phenotype.

Answer 4

A white cat and a black cat having grey kittens.

Answer 5

A red flower and a yellow flower mating to produce an orange flower.

Answer 6
