Answer:
1/4 or 1/2 depending on mating partner of F2
Explanation:
Assuming that the F1 parent Rr mated with a plant with the RR, Rr or rr genotype the F2 offspring would have the following genotypes:
Rr x RR= 1/2 RR, 1/2 Rr
Rr x Rr = 1/4 RR, 1/2 Rr, 1/4 rr
Rr x rr = 1/2 Rr, 1/2 rr
The F2 generation with the RR genotype could not be the parents of the F3 generation because to have individuals with the rr genotype the F2 generation would have to mate with a plant that is either Rr or rr in which case the fraction of the population with the stripe rust phenotype will either be 1/4 or 1/2, respectively.
Answer:
I believe the answer would be A
Explanation:
You would have more fossils of animals that lived longer time ago than recent one bc they would be more older and more beneath the ground.And for animals to fossilize takes a long time so more older animals would be fossils
The correct answer would have to be 2 because it is on subject and is factual
Answer:
18
Explanation:
6 in C6H12O6 and 12 (6×2) from O2
Therefore, 12 + 6 = 18
C. The ecosystem but have limited resources.
Limited resources=intra and inter specific competition= the fittest survive and pass on their successful genes
