Elodia [21]

The right option is; C. They are controlled by more than one gene  

Traits such as skin color, human height and eye colour are known as polygenic traits. These traits have wide variation throughout the human population and are controlled by two or more genes. For example the human height is controlled by at least three genes with six alleles. The quantities of the genes are usually large but often have a little effect.

Tay-Sachs, which is a recessive lethal disease, results only when individuals possess two copies of the disease-causing allele.
VashaNatasha [74]

Answer:

a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.

Explanation:

Tay-Sachs, which is a recessive lethal disease  ---- Let say the recessive lethal diseases is s

∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.

Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.

Let show an illustration for the above statement.

Let the heterozygous individual be Ts, if Ts cross with another Ts;

we will have:

Ts × Ts

         T          s

T        TT        Ts

s        Ts          ss

the offspring are TT,Ts,Ts,ss

We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
