Snap dragon flower color displays incomplete dominance. Which is the likely phenotypic ratio of the F2 progeny resulting from a monohybrid cross of true-breeding parents with white and red flowers?
Group of answer choices
- 4 pink
- 3 white : 1 red
- 3 red : 1 white
- 2 red : 2 white
- 1 red : 2 pink : 1 white
The fruit color of eggplants is an example of incomplete dominance since crossing deep purple eggplants with white
eggplants results in eggplants of a light violet color.
Construct a Punnett square and report phenotypic and genotype ratios of the offspring when a deep purple
eggplant and a white eggplant are crossed

- Which example correctly reflects co-dominance and incomplete dominance? A Codominance - blood type A, in a person carrying allele A and allele O, and A is dominant to O; only antigen A is expressed on red blood cell surface of people with IAi genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show both, red and white phenotype simultaneously (patchy appearance of the flower petals). B Codominance - blood type AB, where antigen A is dominant to B; only antigen A is expressed on red blood cell surface of people with IAIB genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show red phenotype. C Codominance - blood type AB, where antigen B is dominant to A; only antigen B is expressed on red blood cell surface of people with IAIB genotype.Incomplete dominance - red and white flower color inheritance of snapdragons, where the heterozygotes show white phenotype.…arrow_forwardBlack fur in mice is dominant to white fur. Short tails are dominant to long tails. A mouse that is heterozygous for both fur color and tail length is crossed with a white, long-tailed mouse.

- In Andalusian chickens, feather côlor is inherited by incomplete dominance. If one parent with black feathers (BB) is crossed with a white feathered parent (WW), all of the offspring will have blue feathers (BW). What is the probability of producing blue feathered offspring when crossing a blue-feathered hen with a white feathered rooster? * 50% 100% 25% 75%arrow_forwardThe dominance pattern of a gene can be determined from the phenotypes of the parents and offspring. In the examples below, assume that each parent is homozygous for the specific allele and that the progeny are heterozygous. Classify each example as either complete dominance, incomplete dominance, or codominance. Complete dominance Incomplete dominance Codominance Answer Bank A black sheep and a white sheep produce a gray lamb. A white cow and a red bull have a calf that is white with red spots (roan colored). A mother with type A blood and a father with type B blood have a daughter with type AB blood. A pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers. A moth with red wings and a moth with yellow wings produce a moth with orange wings.arrow_forwardDifference between co-dominance and incomplete dominance?arrow_forward
