Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
Answer:
The possible genotype of this cross is RW
Explanation:
This question involves a single gene coding for radish color. The allele for red radish (R) is incompletely dominant over the allele for white radish (W), hence, a third intermediate phenotype is formed when they combine (RW).
In this cross, a pure-breeding red radish (RR) is crossed with a pure breeding white radish (WW) to create the F1 offspring. The red radish will produce gametes R while the white radish will produce gametes W, hence, using a punnet square (see attached image), the F1 offspring will have the genotype: RW.
Homozygous for allele A and heterozygous for allele B. So the answer would surly be D.
