Cloud [144]3 years ago
4 0

Answer:

Explanation:

That's quite a bit of points. Offer 20 next time (which shows up as 10).

Not all experiments lend themselves to this, but the best ones do. Make predictions. The startling experiments (the best of them) certainly allow you to make predictions

Most of the time, experiments confirm what was originally thought. It is, however, the best answer among this bunch.

A is also possible, but not always. I will stick with D, but I think others will pick A.

3. If a daughter has an X-linked recessive disorder, such as color-blindness, she inherited the
Lubov Fominskaja [6]

Answer:

She inherited the trait from C: both parents.

Explanation:

The daughter, being female, has the chromosomes XX. Since the disorder is <em>recessive</em>, both of the chromosomes need to have the disorder's allele in order for it to activate. The daughter's chromosomes can be labeled as X(c)X(c); where the c stands for the color-blindness allele. She needs one X chromosome from the father, and one X chromosome from the mother. Both of these chromosomes contained the (c) allele, as said before, so the mother has one X(c) and the father has one X(c). This means that she inherited the trait from both parents. The final answer is C.

Explain why a person with an allele for a particular trait may not have a phenotype that shows that trait.
Readme [11.4K]
This is because maybe that allele for the trait is recessive and the person is heterozygous. 

If the person is heterozygous, it means that they have both the dominant and recessive allele for a trait. And by dominant and recessive, if dominant allele exists, no matter if recessive allele exists or not, the characteristic controlled by the dominant allele must be shown. This is their phenotype, which is the observable characteristics. 

For example, there are 2 alleles for controlling the eye color. Brown allele is dominant, while blue is recessive. Just like the question above, if the person has an allele for blue eye color, but they have the brown color allele too, their phenotype would be brown eye color, as the brown color is dominant over blue eye color. This matches the requirements of having the allele for a particular trait but not showing the phenotype of that.
