Bio 212 discussion-Homework #2 Please answer each question completely and show work when necessary. 1) What is the difference between incomplete dominance and codominance? A recessive allele in tigers causes the white tiger. If two normally pigmented tigers are mated and produce a white offspring, what percentage to have normal pigmentation? 2) of their remaining offspring would be expected What ratio of offspring would be expected from a cross of pea plants that are heterozygous for both stem height and pod color? Assume that tall is dominant to dwarf in determining stem height and green is dominant to yellow in determining pod color. 3)Explanation / Answer
Incomplete dominance =is a form of intermediate inheritance in which one allele For a specific trait is not completely expressed over its paired allele.this results in third phenotype .In which the expressed physical traits is a combination of the phenotypes of both allele.
Is a perspective of gene action when the heterozygote can be distinguished from the homozygotes.
Example -this was first studied in flowers color of mirabilis jalapa or four o'clock plant. Red flowers are Incompletely dominant Over white flowers ,the heterozygotes being pink.
Codominance = is a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed.this results in offspring with a phenotype that is neither dominant nor recessive.
Codominance is qualitative perspective of gene action where both alleles are expressed .
Example -ABO blood group system
