According to the pedigree chart which statement must be true

Asked by maham237 @ in Biology viewed by 339 People

According to the pedigree chart, which statement MUST be true?
A)
Only male offspring can inherit the disease.

B)
The mother in the original parental generation is a carrier for the disease.

C)
Both the mother and father in the original parental generation are carriers.

D)
The chances of inheriting the disease decrease with each successive generation.

Answered by maham237 @



Answer:

B

Explanation:

This is because the original male is not affected by the disease. In the second generation they have a female child who is a carrier of the disease because she passes it down to her son, but she is not affected. Seeing how all males that carried the disease were affected at some point the disease must lay dormant in female carriers but not males. This means the original father cannot be a carrier of the disease. Hope this helps!
