Answer:

-Makes roots to grow downwards in soil

-Allows root to anchor the plant in soil and to absorb the maximum amount of water and minerals from the soil.

Explanation:

Gravitropism is the growth movement in response to gravity. It allows the roots of the plants to grow downwards in the soil. The growth of roots in soil help to anchor the plant to the substratum. It also makes roots to grow deep down in the soil to absorb the maximum amount of water and minerals to support growth and development of the plant.

Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (a
PilotLPTM [1.2K]

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
