A malaria outbreak causing allele frequencies to change is an example of

1 answer:

6 0

This would be an example of a mutation, because the changing of allele frequencies would be a change within the gene itself, which would be a mutation in the DNA. This is evidenced by the fact that there is now a form of human resistance to malaria, due to changes within human DNA itself.

How is a recessive allele different from a dominant allele apex?

Mnenie [13.5K]

For the trait that is coded by a recessive allele to be expressed, the must be homology, which means that an offspring has to inherit that recessive allele from both its parents.

A dominant allele will dominate over the recessive allele, so for the trait coded by a dominant allele to be expressed, the offspring only needs to inherit the allele from one of its parents.

For example: "R" is brown eyes, "r" is blue eyes.
Now you get one R from each of your parents.
RR (homozygote) = brown eyes
Rr (heterozygote) = brown eyes
rr (homozygote) = blue eyes

In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour.

liraira [26]

Answer:

Natural selection will select the type of ostriches that can run up to 40 mph.

Explanation:

According to the theory of natural selection, organisms with favorable traits following their environment are more likely to reproduce. In doing so, they pass on the better traits to their next generation for the survival of their species.

This process allows organisms to adapt to their environment. And the survival of species is assured.

Here, the type of ostriches that run slow probably fall prey to the jackals. To maintain survival, the ostriches reproduce and lay eggs. If out of almost a dozen eggs, one or two are left to hatch than the chances of their survival will greatly be affected if the hatching ostriches are of the slow-running type.

Therefore, natural selection may stay in favor of fast-running ostriches to hatch.
