Question

Inheriting two copies of a recessive allele causes an individual to die before reaching sexual maturity. How is it that this recessive allele can be passed on from one generation to the next? A. Heterozygous individuals can pass on the recessive allele because they do not die from having only one copy of the allele. B. Two homozygous dominant parents will not give the recessive allele to their offspring , so all will reach sexual maturity . C. Homozygous dominant individuals usually live past sexual maturity to pass on the dominant allele to their offspring . D Two heterozygous parents who have reached sexual maturity will not give the recessive allele to their offspring so all will reach sexual maturity .

Answer 1

Answer:A). Heterozygous individuals can pass on the recessive allele because they do not die from having only one copy of the allele.

Explanation: Since inheriting two copies of a recessive allele causes an individual to die before reaching sexual maturity, the recessive allele can be passed on by individuals who are heterozygous for the allele (having one dominant allele and one recessive allele) because heterozygous individuals are not affected and so they do not die but survive into sexual maturity.
