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 / sujay
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

A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
