Answer:

The correct answer is D.

Explanation:

The Ras Proto-Oncogene is a gene found in normal cells, which by the single point mutation mentioned in the question, can turn into Oncogene. Because Proto-Oncogene is a gene that controls and regulates the division of the cell, a mutation in this gene leads to uncontrolled cell divisions which then leads to cancer. The correct answer is D since RAF-Activation describes "Rapidly Accelerated Fibrosarcoma, fibrosarcoma being a cancer which affects fibrobalst cells.

I hope this answer helps.

The dominant allele is D and causes dimples and the recessive allele is d and causes no dimples. How would a geneticist describe
SSSSS [86.1K]

A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.

<h3>Dominant and recessive alleles</h3>

In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.

An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.

In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.
