- In a sexually reproducing population, the genes are present in different forms or alleles.
- The different alleles are present on different copies of the same chromosomes. In a normally diploid sexually reproducing population like humans, each individual has 23 pairs of chromosomes.
- Thus, there are two copies of each chromosome.
- One of the chromosomes (of each pair) comes from the father through male gamete and the other chromosome (of each pair) comes from mother through the female gamete. After the process of fertilization, the zygote is produced having 23 pairs of chromosomes, with alleles for a trait present on the homologous pair.
So, the correct answer is 'Copies of the same chromosome'

Explanation:
The two versions of a trait brought in by the male and female gametes are situated on copies of the same chromosome.
Chromosomes and Traits:
Chromosomes are thread-like structures found inside the nucleus of cells that carry genetic information in the form of genes. Genes are segments of DNA that contain instructions for specific traits or characteristics.
The Male and Female Gametes:
Gametes are reproductive cells, such as sperm and egg cells, that are involved in sexual reproduction. During the formation of gametes, a process called meiosis occurs. Meiosis involves the division of cells, resulting in the production of gametes with half the number of chromosomes as the parent cell.
The Two Versions of a Trait:
Each trait or characteristic is determined by a pair of genes, with one gene inherited from each parent. These genes can have different versions or alleles. For example, the gene for eye color can have versions for blue eyes and brown eyes.
Location of Trait Versions:
The two versions of a trait brought in by the male and female gametes are located on copies of the same chromosome. This means that the alleles for a particular trait are found on the corresponding chromosomes from each parent. For example, if a person inherits a blue eye allele from one parent and a brown eye allele from the other parent, these alleles will be located on copies of the same chromosome.
Sex Chromosomes:
Sex chromosomes, such as X and Y chromosomes, determine the sex of an individual. In humans, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). However, the location of the alleles for a trait is not specific to the sex chromosomes. The alleles can be located on any of the chromosomes, including the sex chromosomes, as long as they are copies of the same chromosome.
Therefore, the correct answer is option 'D' - copies of the same chromosome. The two versions of a trait brought in by the male and female gametes are located on copies of the same chromosome, regardless of whether they are sex chromosomes or other chromosomes.
