Question

The phenotypic variation in the trait "coat color" in mice is passed from a parent to their offspring via _______________. Select one: a. differences in how well the trait benefitted the parent b. differences in mRNA sequences in different parents c. differences in proteins made by different parents d. differences in DNA sequences in different parents

Answer 1

Answer:

d. differences in DNA sequences in different parents

Explanation:

The picture below shows a Mainland mouse and a Beach mouse with differences in DNA sequences in different parents.

Phenotype can be defined in these light;

– as the appearance of an organism based on a multifactorial combination of genetic traits and environmental factors, especially used in pedigrees.

– as any observable characteristic of an organism, such as its morphological, developmental, biochemical or physiological properties, or its behavior.

Some of this physical traits are a mere result of the proteins produced.

Mice with this DNA sequence GCGTTGGAC have dark coats — Mainland mouse

Mice with this DNA sequence ACGTTGGAC have light coats — Beach mouse

• Genetic information flows from DNA to RNA to proteins.

Arg, Asn, Leu — Mainland mouse

Cys, Asn, Leu – Beach mouse

• Differences in genotype may cause differences in phenotype

The phenotypic variation in the trait "coat color" in mice is passed from a parent to their offspring via the differences in DNA sequences in different parents.
