Alja [10]

Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The ability to taste the chemical PTC is due to a single gene in humans.
Ganezh [65]

0:3:1

Explanation:

Tasters have the dominant allele for the itter taste of PTC, they can be homozygous TT and heterozygous Tt.

Non-tasters are supposed as autosomal recessive characters

they are homozygous recessive tt when expressed

Given in the equation two heterozygotes parents would produce offspring with the trait in the following ratio.

Tt (parent 1)

Tt (parent 2)

 If a punnet square is made

    T      t

T  TT    Tt

t    Tt     tt

The phenotypic character is in the ratio of 0:3:1

There will be 25% chances of recessive trait of non-tasters in the progeny of heterozygous parents.
