Tumor-suppressor genes help prevent uncontrolled cell growth. One that is found mutated (and therefore nonfunctional) in more th
Paha777 [63]

Answer:

p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.

Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.

If present, the ________________ allele will always be expressed as the phenotype.
k0ka [10]

Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.

In cats, black fur color is caused by an x-linked allele; the other allele at this locus causes orange color. The heterozygote i
Luden [163]

The offspring that will be produced in the cross would have tortoiseshell fur.

<h3>X-linked traits</h3>

In cats, the male is XY while the female is XX.

Assuming that black fur is caused by the allele B and the orange fur is caused by A

A black female will have the genotype X^BX^B

An orange male will have the genotype X^AY^A

Crossing the two:   X^BX^B    x     X^AY^A

Offspring: X^BX^A, X^BY^A, X^BX^A, and X^BY^A

X^BX^A = tortoiseshell fur female

X^BY^A = tortoiseshell fur male
