which statement below decribes a componet of sexual reproduction
one parent passesdown the majority of genes
each parent has two alleles per trait and passes one allele
each parent has two alleles and they pass both
only dominate alleles are passed
Each parent has two alleles per trait and passes one allele.
The statement that describes a component of sexual reproduction is: "each parent has two alleles per trait and passes one allele."
The statement that describes a component of sexual reproduction is: "Each parent has two alleles per trait and passes one allele."
To understand why this statement is correct, it's important to understand the basics of sexual reproduction. In sexual reproduction, offspring are produced by the fusion of gametes (reproductive cells) from two parents. Each parent contributes half of the genetic material required to create a new individual.
One way genetic information is passed down is through alleles. Alleles are alternative forms of a gene that produce different variations of a specific trait. For each trait, an individual typically has two alleles, one inherited from each parent.
When a parent reproduces sexually, they pass down one of their two alleles per trait to their offspring. This ensures that the offspring receives a combination of genetic material from both parents, resulting in genetic diversity and variation within a species.
It's important to note that during the process of passing down alleles, both dominant and recessive alleles can be inherited. Dominant alleles are expressed and mask the presence of recessive alleles if present. The inheritance of alleles determines the traits and characteristics that an offspring will possess.
So, the statement "Each parent has two alleles per trait and passes one allele" accurately describes a key component of sexual reproduction.
