Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation. What is true about the mother?

Answers

The true statement about the mother of this family tree is that she is a carrier for color blindness.

The correct option is (B).

What is color blindness?

Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.

It is a condition in which a person is unable to distinguish between different colors.

The most common colors are greens and reds, but it can also happen with blues.

This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.

Thus, option (B) she is a carrier for color blindness is correct.

since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.

Answer:

Natural selection

Explanation:

Natural selection favors the individuals carrying the adaptive variations and allows them to reproduce more as their beneficial variations impart them the survival advantage. These individuals with beneficial adaptive traits reproduce more and produce a large number of progeny, all carrying the useful adaptive features of the parents.

Hence, natural selection favors individuals with beneficial variations. The differential rate of reproduction of the favored individuals allows inheritance of favored variations to the future generations.

That process is called natural selection

What strand of mRNA would be made during transcription using the dna strand shown belowCGA TCT

Answers

Answer: GCT AGA

Explanation:

The complementary binding of the nitrogenous bases takes place in the process of DNA replication.The complementary mRNA strand is GCT AGA. The whole process of DNA replication consists of two steps: Transcription and translation.

The transcription can be defined as the process by which the DNA is converted into mRNA and then the information for the protein synthesis is carried by the mRNA.

The mRNA undergoes the process of splicing to produce the desired protein. This step is known as translation.

The answer is probably GCU AGA : )
