One parent passes down the majority of genes an offspring will receive.
One parent passes down the majority of genes an offspring will receive.
Each parent has two alleles per trait and passes one allele to their offspring.
Each parent has two alleles per trait and passes one allele to their offspring.
Only dominant alleles are passed to offspring.
Only dominant alleles are passed to offspring.
Each parent has two alleles and they pass both down to their offspring.
Each parent has two alleles per trait and passes one allele to their offspring.
The correct statement is:
Each parent has two alleles per trait and passes one allele to their offspring.
The statement that correctly describes a component of sexual reproduction is: Each parent has two alleles per trait and passes one allele to their offspring.
To understand why this statement is correct, it is important to first understand the basics of genetics and sexual reproduction. In sexual reproduction, offspring inherit traits from both parents, resulting in a combination of genetic material.
Genes are segments of DNA that carry instructions for specific traits. Each gene can have different forms, or alleles, which can determine variations in traits. For example, the gene for eye color can have alleles for blue, green, or brown eyes.
In humans, each parent has two alleles for each trait because they inherit one allele from each of their parents. When they reproduce, they pass on only one of these alleles to their offspring. The specific allele that is passed on is determined by mechanisms such as random assortment and genetic recombination.
Therefore, the statement that correctly describes a component of sexual reproduction is that each parent has two alleles per trait and passes one allele to their offspring. This ensures that the offspring inherit a combination of genetic material from both parents, resulting in genetic diversity.
