$A$ human male produces sperms with the genotypes $AB, Ab, aB,$ and $ab$ pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of this person?

The phenotypic ratio of a dihybrid cross is ....

$A, B, D$ are three independently assorting genes with their recessive alleles $a, b, d$,respectively. $A$ cross was made between individuals of $Aa bb DD$ genotype with $aa bb dd$. Find out the types of genotypes of the offspring produced.

To determine the different types of gametes produced by a pea plant with the genotype $AaBb$,with which genotype should it be crossed?

When a dihybrid plant with dominant traits of red color and tall height $(RrTt)$ is crossed with a recessive plant having white color and dwarf height $(rrtt)$,what will be the phenotypic ratio of the offspring for red-tall,red-dwarf,white-tall,and white-dwarf respectively?

In a dihybrid cross,considering the characteristics of the $F_1$ generation obtained from the parental generation and the $F_2$ generation,how many types of gametes (pollen grains) will be produced by the $F_1$ generation?
