Question

drag the tiles to the correct boxes to complete the pairs.
match the genes with their linkage ability.

genes close to each other genes on different chromosomes

genes apart from each other,
but on the same chromosome

unlinked genes

not so strongly linked genes

strongly linked genes

Explanation:

• Unlinked genes: Genes on different chromosomes do not have linkage as they assort independently during meiosis. So unlinked genes match with genes on different chromosomes.
• Not so strongly linked genes: Genes that are apart from each other on the same chromosome have a higher chance of crossing over, so their linkage is not strong. Thus, not so strongly linked genes match with genes apart from each other, but on the same chromosome.
• Strongly linked genes: Genes close to each other on the same chromosome have less chance of crossing over, so they are strongly linked. So strongly linked genes match with genes close to each other.

Answer:

unlinked genes → genes on different chromosomes
not so strongly linked genes → genes apart from each other, but on the same chromosome
strongly linked genes → genes close to each other
