Answer:

He would need to cross one homzygous red (RR) and homzygous white (rr)

Explanation:

Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.

According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.

A. Populations of native wetlands plants will recolonize the land.

Explanation:

From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted<em> because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.</em>

If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.

Hence, the correct option is A.

What is the answer with explaining

pychu [463]

Answer:

All EeWw (100%)

Explanation:

This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for earlobe but homzygous recessive for hairline i.e. (EEww).

The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:

eeWW - eW, eW, eW, eW

EEww - Ew, Ew, Ew, Ew

Using this gametes in a punnet square, the following proportion of offsprings will likely be produced:

All EeWw
