Heterozygous round and yellow seeded pea plants were selfed and a total of $800$ seeds were collected. What is the total number of seeds with the first dominant trait (round) and the second recessive trait (green)?

The dihybrid test cross ratio of $1: 1: 1: 1$ proves that

In rabbits,black skin $(B)$ is dominant over brown skin $(b)$ and short hair $(S)$ is dominant over long hair $(s)$. $A$ homozygous black,short-haired male is crossed with a homozygous brown,long-haired female. All $F_1$ offspring are heterozygous black,short-haired. If the $F_1$ male is crossed with an $F_1$ female,what is the percentage of homozygous black,short-haired offspring in the $F_2$ generation (in $\%$)?

In $F_2$ generation,a phenotypic ratio of $1:1:1:1$ exhibits

In Mendel's dihybrid cross,what is the probability of obtaining a homozygous recessive plant in the $F_2$ generation?

$A, B, D$ 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.
