Question

what non-Mendelian pattern of inheritance occurs when the phenotype of the offspring somewhere in between the phenotypes of both parents and a completely dominant allele does not occur A). dominance B). codominance C). multiple alleles D). incomplete dominance​

Answer 1

Answer:

it's D) Incomplete dominance

Answer 2

When the phenotype of the offspring somewhere in between the phenotypes of both parents and a completely dominant allele does not occur D). incomplete dominance​.

Explanation:

• Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotypes of both parents a completely dominant allele does not occur.
• For example when red snapdragons are crossed with white snapdragons the F1 hybrids are all pink heterozygotes for flower color.
• Polygenic means many genes are necessary for the organism to develop the trait.
• For example at least three genes are involved in making the reddish brown pigment in the eyes of fruit flies.
• Polygenic traits often show a wide range of phenotypes.
• Codominance as in human blood type is a form of inheritance in which both alleles are expressed equally in the phenotype of the heterozygote.
• Such modes of inheritance are called non Mendelian inheritance and they include inheritance of multiple allele traits traits with codominance or incomplete dominance and polygenic traits.
