Answer:
In the F1 generation
RR = 0%
Rr = 50% (or 0.5)
rr = 50% (or 0.5)
Explanation:
A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.
A white flowering plant has the genotype rr. It is homozyogous for the white allele
A punnet square of the cross is shown.
The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
The answer is D, The structure was probably functional in some ancestor of the modern organism. Vestigial structures are structures that have remained from ancestors but have no function in modern times.

You sound unsure of yourself and you list negatives (not super negative but they’re not great) attributes about yourself. try listing more positive things about yourself besides you being “bored”, “annoying”, or “lazy”. Maybe you have a hobby like drawing or playing games, add things like that
it can’t survive the vacuum of space, zero temperatures and radiation and the DNA may be the missing link to long distance space travel
