Agene on a chromosome lies close to another gene controlling a different trait. this indicates that the genes are _. the first gene contributes to the expression of the second gene. this indicates _?

One gene on one chromosome is next to another gene that controls a different characteristic. This indicates that genes are strongly linked.  When the genes are very close on the same chromosome, they are said to be linked. This means that the alleles, or the gene versions, put together in a chromosome will be more often inherited as a unit than separately. The first gene contributes to the expression of the second gene. This indicates non-epistatic gene interaction . We say that gene interaction is non-epistatic when two or more genes interact, but no allele prevents the expression of another, but the first gene contributes to the expression of the second gene.

Tta ttc ctg i hope its right.
