The protein which encodes the gene belongs to a family of protein that have 3 members P⁵³,P⁶³ and P⁷³.

P⁵³ is known as tumor suppressor protein that is responsible for apoptosis of cells.

This protein is encoded by TP53 gene.This is important and play a crucial role in cell cycle an thus functions as tumor suppressor which involved in preventing  cancer.Thus it is called called as "Guardian angel gene".

BigorU [14]

Answer:

b

Explanation:

<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>

Heterozygous wild-type male fish would be Aa

Golden female fish would be aa

     Aa    x    aa

  Aa   Aa    aa    aa

2/4 Aa = silver-white

2/4 aa = golden color

<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>

The correct option is b.
