Question

Normally, how many chromosomes are required to determine the outward expression of a trait?

A.only one
B.any two
C.a homologous pair
D.two pairs

Answer 1

the chromosomes that hold the genes must be homologous. Since it cannot be any 2 chromosomes.

Answer 2

why because in somatic cells, there are 2 chromosomes that hold the same gene. if the gene is dominant, it requires one gene on 1 chromosome. if the gene is recessive and is expressed, it requires 2 genes from the 2 chromosomes. if the gene is dependent upon more than one gene, eye color, blood type, etc. then the genes may be on more than one chromosome. Since chromosomes don't determine the traits. the genes on the chromosomes determine the trait.
