Answer:

Naturally selected organisms will survive and reproduce better adapted to the environment. This indicates that this model organism's beneficial allles are passed to offspring. The selection cycle contributes to adaptation for several years.

Explanation:

Predict what the calf produced in a union between each of these parents might look like. Explain your answers.
Charra [1.4K]
We know that purebred means that the organism contains the same alleles for the trait and hybrid means that it contains two different alleles for the trait. Dominant means that it will be shown in a hybrid and a purebred, but recessive traits will only be shown in purebred recessive organisms.

a) The offspring of a purebred white (recessive) cow and a purebred brown (dominant) bull, would be all hybrid brown (dominant). This is because as I stated above, dominant traits are shown when the offspring has both dominant and recessive alleles for the same trait.

b) The offspring of a purebred brown (dominant) cow and a purebred brown (dominant) bull would all be purebred brown (dominant). This is because if both of the parents have only alleles that code for brown color, the only color that the offspring can be is brown.

c) The offspring of a purebred white (recessive) cow and a purebred white (recessive ) bull would all be purebred white (recessive), for the same reason stated above in part b), the only difference being that the alleles are recessive and code for white color instead of being dominant and coding for brown color.

d) The offspring of a hybrid brown (dominant) cow and a purebred white (recessive) bull would be half hybrid brown (dominant) and half purebred white (recessive). This can be seen best if you set up a Punnett Square, which is a diagram that shows allele frequencies in offspring. This shows you that the chance that the offspring get the dominant allele from the mother cow is 50%, thus 50% would be hybrid brown (dominant), as the father can contribute only a recessive white allele. The other 50% would be purebred white (recessive) because the mother cow would be contributing a white allele and so would the father.

Hope this helps! :)

After injuring his knee kai began having pain and numbness in his lower leg. the doctor said the injury damaged nerves that run
Leno4ka [110]

Damage to the nervous system is causing Kai to have pain and numbness.  

<h3><u>Explanation:</u></h3>

Kai injured his knee. We know that the posterior surface of the knee has the quadrangular fossa which is guarded by the tendons of hamstrings anteriorly and by the two heads of gastrognemus muscle below. There are several nerves running down the leg through this region.

Any trauma to this fossa can cause these nerves to get damaged. Thus it can lead to numbness of lower limb. Proper physiotherapy is required to recover as soon as possible. Else that can even lead to paralysis of lower limb.

"Darwin's finches" reside on the galapagos islands. Each species has a different type of break, however, they can all be traced
Lilit [14]

Answer:

The correct answer would be adaptive radiation.

It is a natural phenomenon by which ancestor species diversify into new forms as a result of adaptation towards changing the environment, limited or different resources, new challenges or new ecological niches.

For example, Darwin's finches faced new niches, different environment, different types of food resources due to which they adapt to different species bearing beaks of different shapes and sizes.
