Alleles: they are alternatively occuring any one of two or more genes at a given site on a chromosome.Alleles may occur in pairs or many multiple alleles might affect the expression of a particular trait.
Eg.ABO blood group,A person with AB blood group has allele A and B present in it.

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...

An autosomal dominant gene is associated with several traits related to the olfactory system. One trait is that people with at least one copy of the dominant allele can smell a specific chemical when it is present. People with two copies of the recessive allele cannot smell the chemical. Being able to smell or not smell the chemical when a person has two copies of the dominant allele is an example of: Codominance Epistasis Expressivity Penetrance Phenocopy The concentration of...

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31. If the dominant alleles for stem color and fasciation are commonly located on the same chromosome, how...
