Answer:
75% probability
Explanation:
The father have the trait of sickle cell anemia which means he is a sickle cell dominant with a trait of dominant SS ( meaning he has displays the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele i.e homozygous). While the mother is heterogygous which means that she has one abnormal allele of the hemoglobin beta gene represented as As.
Based on this notion, upon crossing of the traits the probabilities are<em> 75% Heterogygous trait and 25% homoxygous traits (i.e As, As, As, SS)</em>. Meaning 75% of the children will be unaffected by the Sickle cell anemia, while 25% will be affected by the anemia.

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
Answer:
generic variation helps species survive because it gives there offspring there traits to survive
