Question

In a plant that has red flowers, red flower color, R, is completely dominant to white flower color, r. If the plant is heterozygous for flower color, which alleles will be carried by the gametes it produces?

a)R only

b) r only

c) R and r

d) Rr only

explain pleaseee!!!

Answer 1

Since the plant has red flowers and we now that "red" (R) is a completely dominant allele  this means it could either be RR (homozygous red) or Rr (heterozygous with one red allele and one white one).  We are then told it is heterozygous which means it is Rr.  When the cells divide each gamete will have one of the alleles which means some will be R and some will be r.

Answer 2

The alleles it produces will have both R and r (c). This is because the two different alleles segregate from each other when the cell divides in meiosis. I.e. The R allele will go to one gamete while the r allele will go to the other
