creativ13 [48]3 years ago
8 0

Explanation:

when meiosis occurs, a half the set of chromosomes from the original cell go to each daughter sex cell produced.

when mitosis occurs, the chromosomes are duplicated so there are two copies of the same genes and each copy is given to the daughter cells produced.

Hope this helps :)

The image shows the cross between two parents who are carriers for sickle cell anemia, a recessive genetic disorder that affects
podryga [215]

Answer:

<em>Both the parents are carriers of sickle cell anaemia.</em> A carrier can be described as a person who carries a diseased causing allele but the allele is not functional in the body of the person due to the dominant allele suppressing its activity. Such kind of people might produce children actually having the disease.

In the above scenario, <em>there is a 25% chance that the children born will be normal. </em>

<em>There is a 50 percent chance that the children born will be carriers, like the parents.</em>

<em>There is a 25% chance that the child born from these parents might have sickle cell anaemia.</em>

Which type of natural selection occurs when an intermediate phenotype is favored?
klasskru [66]

Answer:

The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.

Explanation:

There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.

A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.

A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.

The extinction of snakes from the population will lead to decrease in genetic variation.
