The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.
R r
r
r
The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.
R r
r Rr rr
r Rr rr
Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.
Hope this helps!
I think the answer should be B as well hope it helps
Answer:
Natural selection is least likely to occur in this population if:
- The resources are continuously available
For a species to survive in an area, it is essential that the place has enough resources like nutrients, space, water etc. If these resources are available then there will be less chances of competition which will lead to lesser chances of natural selection.
- The number of of death rates is equal to the number of of birth rates
In an balanced ecosystem, the number of birth rates is equal to the number of death rates for a population. If the number of death rates is lesser to the number of birth rates then the competition for resources will lead to natural selection.
