Question

The total number of linkage groups in an organism is exactly equal to:

Options

• Its diploid chromosome number

• Its total number of genes

• Its haploid chromosome number

• Its number of homologous pairs multiplied by two

Answer 1

The total number of linkage groups in an organism is exactly equal to its haploid chromosome number. This is because each chromosome in the haploid set represents one linkage group containing all its associated linked genes.
