Answer:

D. is transcriptionally inactive.

Explanation:

Euchromatin is the part of chromosomes which are loose in form and are involved in the transcription process because these are available for the transcription into specific protein products. On the other hand, heterochromatin is the region of chromosomes that appears dark in staining process. This region is transcriptionally inactive because of the DNA template in the DNA-protein complexes and which means that genes present in the region are not active and not involved in the process of transcription.

Hope it helps!

A man with normal vision marries a color-blind woman. Red-green color blindness is an X- linked recessive disorder. They have a

jeyben [28]

Answer: The probability is 100%.

Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:

If it is a boy, he inherites the chromosome Y from his father and X from his mother;
If it a girl, she inherites X from her father and X from her mother;

In the question, the woman is color-blind, which means she carries the recessive alleles: $X^{d}X^{d}$

The man, on the other hand, is normal, so his X-linked genotype will be: $X^{D}Y$ .

Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one $X^{d}$ from her mother and one $X^{D}$ from her father.

So, the daughter's genotype can only be heterozygotic $X^{D}$ $X^{d}$ in other words, the probability is 100%.

Why should scientist avoid bias during experiments?

kipiarov [429]

If a scientist is biased, then their result could be flawed or wrong; not to mention, it discredits their result from that experiment, and any other that they have participated in.
