In a dihybrid cross,what is the proportion of $RrYy$ offspring obtained from the selfing of an $RrYy$ plant (in $/16$)?

In Duroc-Jersey hogs,skin color is determined by two pairs of alleles,$R/r$ and $S/s$. Any genotype containing at least one dominant $R$ allele and one dominant $S$ allele results in a red skin color. $A$ double recessive genotype $(rrss)$ results in a white skin color. All other genotypes result in a sandy skin color. If a Duroc-Jersey hog with the genotype $RrSs$ is crossed with a hog having the genotype $rrss$,what will be the phenotypic ratio of the offspring?

What type of gametes will be formed by the genotype $RrYy$?

Which law is demonstrated by Mendel's dihybrid cross?

In a cross between yellow round $(YYRR)$ and pure breeding pea plants having green wrinkled $(yyrr)$ seeds,find out the total number of seeds (plants) having yellow colour in the $F_2$ generation out of $16$ offspring.

In a dihybrid cross between $RRYY$ and $rryy$,what is the probability of obtaining $RrYy$ in the $F_{2}$ generation (in $/16$)?
