1.
let genotype for
tongue rolling(T) and unable to rolling (t)
so that men genotype is tt and woman gentotype is Tt
their child has fathers genotype i.e. tt
cross tt x Tt
gives progeny Tt,Tt,tt,tt
purple(P) flowers dominant to white(p)
so that
PP= purple
Pp= purple
pp= white
round (R) seeds dominant to wrinkled (r) seeds
so that
RR= round
Rr= round
rr= wrinkled

2. (4pts) In a strain of Petunia that normally have purple flowers, recessive and dominant mutations at the red color locus (R locus : R+ = wildtype allele, purple) lead to different flower colors. Plants that carry a particular dominant allele Ra have pink petals. Of the individuals that carry one allele of the dominant allele Rb roughly 20% have normally colored purple petals, the remaining 80% show a range of lighter red colors. Individuals that are homozygous for Rb...
