The number of linkage groups in human beings is
Correct answer: B. 23
- A. 46
- B. 23
- C. 22
- D. 44
Explanation
One linkage group corresponds to each kind of chromosome in the haploid set, so humans have 23. The diploid number of 46 counts each homologue twice and is therefore a distractor.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
