In Mendel's dihybrid cross,what percentage of the total $F_2$ progeny had green seeds (in $\%$)?

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)?

In Mendel's dihybrid cross,what percentage of seeds with yellow color were obtained in the $F_2$ generation (in $\%$)?

In a dihybrid cross where two parents differ in their traits,such as yellow seeds $(YY)$ with round shape $(RR)$ and green seeds $(yy)$ with wrinkled shape $(rr)$,how many seeds out of the total $16$ in the $F_2$ generation will be green $(yy)$?

In a dihybrid cross between $AABB$ and $aabb$,the ratio of $AABB, AABb, aaBb,$ and $aabb$ in the $F_2$ generation is:

If a trihybrid cross is performed between two plants with the genotype $AaBbCc$,what proportion of the offspring will have the genotype $aabbcc$?
