The correct answer is B. Gene mutation

Since it would be almost impossible for a gray progeny to be created, this would classify as a gene mutation. Similar thing occurred with people who have blue and green eyes since once long ago only brown eyes existed, and the people who got blue eyes did so as a gene mutation.

Answer:

The genotype of the parents are not given. Let's try to answer this question generally. Let's assume the genotype of both parents to be Bb as genotype is not given.

Explanation:

       B        b

B    BB      Bb

b     Bb      bb

There is a 25% chance that the offspring will have BB genotype.

There is a 50% chance that the offspring will have Bb genotype.

There is a 25% chance that the offspring will have bb genotype.

There is a 75% chance that the offspring will have a dominant trait.

There is a 25% chance that the offspring will have recessive trait.

Phenotypic ratio will be 3:1

Why was water used to dilute the substances instead of another chemical?
BabaBlast [244]
Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

If a cell with 36 chromosomes undergoes mitosis, how many cells will be produced and how many chromosomes
ELEN [110]

Answer:

B. There will be two cells each with 36 chromosomes.

Explanation:

The products of mitosis are called diploid cells, and they each have the complete set of chromosomes. These cells are usually important for activities such as growth, repair etc. They make up our normal body (somatic) cells. Therefore, the answer is 36, only 36 matches the description of genetically identical cells
