Answer:
contain a mutated tumor-suppressor gene.
Explanation:
- A tumor suppressor gene performs the function of regulating the proper division of the cells as well as regulating replication.
The tumor suppressor genes perform the following functions :
- Maintain the stability of the genome.
- Regulate cell growth.
- Regulates cell proliferation rate.
- Whenever the tumor suppressor genes get mutated it would either result in a loss of its function or a reduction in its function which can lead to the abnormal growth of cells.
- Hence, if the DNA is damaged, the cells become crowded and the nutrients run low then this indicates that the tumor suppressor genes are mutated.
If one parakeet is heterozygous, that means it has one dominant gene and one recessive gene (Rr). If the other is homozygous for white feathers, then it has two recessive genes (rr). Crossing these two in a punnet square gives you 50%.

(B) 25% GG, 50% Gg, and 25% gg
<u>Explanation:</u>
Given:
Green is dominant and is coded by G
Albino is recessive and is coded by g
Two corn plants that are heterozygous for color are crossed.
The heterozygous condition of the plant would be Gg.
The cross is shown in the table attached.
According to the punnett square drawn,
The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)
= 25% GG , 50% Gg , 25% gg
Phenotypic ratio = 3 : 1 ( green : albino)
= 75% green, 25% albino
