The haploid chromosome number in pea is:
Correct answer: C. 7
- A. 8
- B. 10
- C. 7
- D. 14
Explanation
The correct answer is 7, which is the haploid chromosome number in peas. This means that each gamete (sperm or egg) contains 7 chromosomes. In contrast, the diploid number, which is the total number of chromosomes in a typical somatic cell, is 14. Options A and B are incorrect as they do not represent the haploid chromosome number in peas. Option D is incorrect because it represents the diploid chromosome number.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
