The question asks us to identify the term used to describe two genes that control the same trait. Let's examine the options provided:
- Homozygous: This term refers to an organism that has two identical alleles for a specific trait. It describes the genetic makeup in terms of similarity and does not directly refer to the two genes themselves.
- Alleles: These are different forms of the same gene that control a particular trait and occupy the same position (locus) on a pair of chromosomes. This is the correct answer, as alleles are precisely the two genes that manage the same trait.
- Heterozygous: This term refers to an organism that has two different alleles for a specific trait. Like homozygous, it describes the genetic composition but is not the term for the genes controlling the trait.
- Genetic recombination: This is the process in which genetic material is rearranged during the formation of offspring, not the term for genes controlling a trait.
Therefore, the correct term for genes that control the same trait is Alleles.

The table given below shows the Lod score values of three different pairs of genes studied for assessing if they are linked pairs:
Gene Pair '1' Gene Pair '2' Gene Pair '3' Lod Score 1 2 3 The following conclusions were made from the data given above:
A. For gene pair 1 the probability of the genes being linked is 10 times more likely than them assorting independently.
B. For gene pair 2, the Lod score 2 indicates that the probability of the genes being linked is twice more likely than assorting independently.
C. The genes of pair 1 and 2, can both be considered as linked, while the genes of pair 3 exhibits independent assortment.
D. The genes of pair 3 can be considered as linked.
