Which statement correctly describes the mechanism of inheritance?

The correct answer is option B, alleles on homologous chromosome determine traits

Explanation:

In a homologous chromosome, the alleles of any trait occupies same position and thus when alleles occupying the same position combine with each other they lead to expression of the trait. In a heterozygous chromosome, the alleles of the same trait occupies different position and thus they are not expressed effectively. In the mechanism of inheritance genes are responsible for expressing any character, therefore allele lying in the homozygous chromosome of genes pair up to express of any characteristics.

chemistry sucks a**

explanation:

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
