sveta [45]

Answer:

Individuals with different alleles for a single trait are classified as <u>heterozygous.</u>

Explanation:

Zygosity is defined as the degree of similarity of alleles for a given trait. Alleles are the variations in the DNA sequence of a gene, that varies from one organism to another.

A diploid organism is homozygous at a gene locus, when both the alleles for a single trait are same. Whereas, a diploid organism is heterozygous at a gene locus, when both the alleles are different for a single trait.

Ans.

Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the  offspring.

Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.

However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
