Suppose you identify a new gene in mice. One of its alleles specifies white fur, another specifies brown. You want to see if these alleles are inherited in a Mendelian pattern, or with incomplete dominance. What crosses would give you the answer?
To explain: The crosses that would provide answer to check if the alleles for phenotype for white fur and brown fur are inherited based on Mendelian pattern of inheritance or non-Mendelian pattern of inheritance.
Concept introduction: Mendelian pattern of inheritance is where the ratio of the phenotypes in the case of monohybrid cross is 3:1 and that of dihybrid cross is 9:3:3:1. Any phenotypic ratio that deviates from the Mendelian pattern of inheritance falls under non-Mendelian inheritance category. Incomplete dominance is a type of non-Mendelian inheritance where the heterozygous phenotype is the intermediate of the homozygous dominant and homozygous recessive phenotypes.
