Biology
1 answer:
ELEN [110]4 years ago
4 0

Answer:

3) offspring with more variety

Explanation:

The reason #3 is the answer to #1 is because variety means change or difference in something and the change was in the environment. Asexual species reproduce with no partner, just their genetics, so there isn't much of a change. Species that reproduce sexually have a higher advantage of reproducing offspring with more variety because there was a "change" in the environment. If that change affected one of the two mating species it could cause variety within the environment.

In a certain plant, fruit color is affected by an epistatic interaction between two genes. The fruit is red in the presence of a
sukhopar [10]

Answer:

15/16 or 93.75%

Explanation:

<em>The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.</em>

Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.

AaBb   x   AaBb

Progeny' Genotype       Phenotype

1 AABB                               red

2 AABb                               red

2 AaBB                                red

4 AaBb                                 red

1 AAbb                                 red

2 Aabb                                  red

1 aaBB                                  red

2 aaBb                                  red

1 aabb                                   white

Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.
