What can explain the phenomenon where two different loci only give a phenotype when they are both mutated at the same time? A. Codominance B. Pleiotropy C. Incomplete dominance D. Redundancy E. Complete dominance
Homework Answers
In this context, the genetic redundancy refers to the phenomenon where two or more genes are involved in the same biochemical function. In other words, there is not only one gene for a determined function, there are more than one. IN this sense, the mutation or defect of one wont promote a significant phenotypic change because there are other genes that can “supply” this absence. For this reason is why, two genes must be mutated in order to express a determined phenotype.

Q1. What is the difference between incomplete dominance and codominance? A. In incomplete dominance, the dominant phenotype is expressed in heterozygotes. In codominance, both phenotypes are expressed in heterozygotes. B. The phenotype reveals the genotype only in codominance. C. In both types of inheritance, the heterozygotes express the phenotypes dictated by both alleles. D. In codominance, both phenotypes are expressed in heterozygotes. In incomplete dominance, the heterozygote shows a phenotype that is intermediate between the two homozygotes. Q2. Based on...

1) What is the molecular basis of dominant and recessive alleles (for complete dominance; ignore incomplete dominance, epistasis, etc.)? To answer this question, consider the following: a) If alleles are copies of the same gene, why are two types of alleles? What differentiates a dominant allele from a recessive allele (at the molecular level)? Be specific (base pairs, transcription/translation method, protein produced, etc.) b) Why is the phenotype determined by the dominant allele in heterozygous genotype? Be specific. c) What...
