In a cross between $TTRr$ and $ttrr$,what percentage of the offspring will be tall with red flowers (in $\%$)? (Assume $T$ is tall,$t$ is dwarf,$R$ is red,and $r$ is white).

In a cross between yellow round $(YYRR)$ and green wrinkled $(yyrr)$ pea plants,find out the ratio between seeds having yellow and green seed colour in the $F_{2}$ generation.

$A$ heterozygous trihybrid plant produces .....

What should be the phenotypic ratio of a test cross between a trihybrid and a homozygous recessive parent?

Which one of the following crosses will have a $1:1:1:1$ ratio of progeny?

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?
