People who can roll their tongues contain a dominant allele
for tongue rolling. If people do not contain the tongue
rolling gene, then they cannot roll their tongue no matter
how hard they try.
Consider the following situation: If a homozygous dominant
tongue roller mates with a homozygous recessive non-tongue
roller, then what is the probability of the offspring
inheriting the tongue rolling gene?
Answer Posted / baba_mailme
CONSIDER THE HOMOZYOUS DOMINANT GENE FOR THE TONGUE ROLLER-
TT AND THE HOMOZYOUS RECESSIVE GENE FOR THE TONGUE ROLLER-tt
Now when the two mates the F1 generations will be Tt(all
the offspring will br hetrozyous dominant). On selfing them
the F2 generation produced will be 75% dominant(TT and Tt)
and 25% recessive(tt).
parents TT X tt
gametes T T t t
F1 generation Tt Tt Tt Tt
on selfing Tt x Tt
gametes T t T t
F2 generation TT Tt Tt tt

In sesame, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant over wrinkled leaf (l). The two characters are inherited independently. Determine the genotypes and phenotypes of the two plants which produce the following progeny: 318 one- pod normal, 98 one-pod wrinkled, 323 three-pod normal and 104 three-pod wrinkled.

In cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why?
