ivann1987 [24]

They are more similar then different. Animal and plant cells have some of the same cell components in common including a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, peroxisomes, cytoskeleton, and cell (plasma) membrane. The main difference is that plant cells have a cell wall while animal cells only have a cell membrane. In addition, plant cells preform photosynthesis, while animal cells preform cellular respiration.

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).
