1. The two versions of a trait (character) which are brought in by the male and female gametes are situated on (a) copies of the same chromosome (b) two different chromosomes (c) sex chromosomes any chromosome

Explanation:

Each diploid individual inherits two copies of a chromosome, one from each parent. Hence the two versions of a trait or alleles of a gene, which are contributed by the male and female gametes are present on a pair of homologous chromosomes.
