Punnett Square for Mendelian Genetics
"a" is a dominant mutant allele of the A gene, and "b" is the recessive mutant allele of the B gene. To see the mutant phenotype, one requires either an "a" mutant phenotype or a "b" mutant phenotype (both mutations are not necessary).
What would the F2 segregation ratio be (wild type to mutant) of the cross of an aabb mutant with AABB wild type?
(Note that Arabidopsis nomenclature is used. Mutant alleles are lower-case whether they are dominant or recessive, wild type alleles are upper-case.)© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/biology/genetics/punnett-square-for-mendelian-genetics-3b6
...ogeny (F1). Crossing AaBb X AaBb would give the F2 generation. The possible gametes for this cross are: AB, aB, Ab, ...
