A mutation occurs in the liver cells of a certain field mouse. Which statement concerning the spread of this mutation through the mouse population is correct?.

Answers

Answer:

The answer is c) It will not spread because it is not in a gamite.

Hope you get it right :)

It will spread to the gametes as somatic cell mutations are not transferred to the gametes. Therefore, option "C" is correct.

What is mutation?

Each organism has its own unique DNA sequence. The sequence of its base pairs can sometimes change. The term for it is mutation. A transformation might prompt changes in proteins deciphered by the DNA. A transformation is an unexpected, heritable change in an organic entity's characteristics.

When a person has altered genes is known as a mutant. The resultant genes having mutations are known as recessive genes. The types of mutations are substitution motion, deletion mutation, point mutation, nonsense, and a frameshift mutation

Therefore, somatic cell mutation is not transferred to the next generation.

In snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink. What would be the chance of getting a red flower if you cross a pink flower with a pink flower?.

Answers

The chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.

WHAT IS INCOMPLETE DOMINANCE?

Incomplete dominance is a type of inheritance in which two alleles of a gene are neither dominant or recessive, hence, a intermediate phenotype is produced.

According to this question, in snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink.

If two pink flowered plants are crossed i.e. Pp × Pp, the genotype of the offsprings that will be produced as follows:

PP (1) - red flowerPp (2) - pink flowerpp (1) - white flower

Therefore, the chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
