suppose you have the monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ration
Arisa [49]

Answer;

The correct answer would be Rr.

In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.

In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.

The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.

Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).

List the reasons why food chains to not send to exceed 4 links
Hitman42 [59]
As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.
