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?

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

CONSIDER THE HOMOZYOUS DOMINANT GENE FOR THE TONGUE ROLLER-
TT AND THE HOMOZYOUS RECESSIVE GENE FOR THE TONGUE ROLLER-tt
Now when the two get crossed the F1 generations will be
three offsprings having tongue rolling character and one
offspring will be recessive homozygous non-tongue roller in
F1 generation.
p1 parents TT X tt
gametes T T t t
F1 generation TT Tt Tt tt
