Which statement below correctly describes a component of sexual reproduction?
A. One parent passes down the majority of genes an offspring will receive.
B. Each parent has two alleles and they pass both down to their offspring.
C. Only dominant alleles are passed to offspring.
D. Each parent has two alleles per trait and passes one allele to their offspring.
D. Each parent has two alleles per trait and passes one allele to their offspring.
D. Each parent has two alleles per trait and passes one allele to their offspring.
To determine which statement correctly describes a component of sexual reproduction, we'll need to analyze each option systematically.
A. One parent passes down the majority of genes an offspring will receive.
This statement is incorrect. In sexual reproduction, both parents contribute genetic material to their offspring.
B. Each parent has two alleles and they pass both down to their offspring.
This statement is incorrect. Each parent has two alleles per trait, but they only pass one allele to their offspring, resulting in a combination of alleles.
C. Only dominant alleles are passed to offspring.
This statement is incorrect. In sexual reproduction, both dominant and recessive alleles can be passed down to offspring.
D. Each parent has two alleles per trait and passes one allele to their offspring.
This statement is correct. In sexual reproduction, each parent has two copies of each gene, represented by two alleles. They pass one allele to their offspring, resulting in a combination of alleles from both parents.
Therefore, the correct answer is D: Each parent has two alleles per trait and passes one allele to their offspring.
