Answer:

The correct answer is C. Mammals can produce milk for their offspring.

Mammals are the members of class mammalia. The word mammalia was derived from Latin word "mamma" which means "breasts" as they had a unique feature i.e. presence of mammary glands.

These glands were evolved from a special types of sweat glands and became specialized in the production of milk, especially in females.

They help the mothers in providing nourishment to the offspring.

Other features of mammals may include four chambered heart, hair and fur, three middle ear bones, etc.

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.
