The genotype of an individual is RrAa. How many different types of gametes will it produce based on the law of independent assortment?
Correct answer: D. 4
- A. 16
- B. 8
- C. 9
- D. 4
Explanation
The total number of gametes that can be produced is given by the formula 2n. Where n represents the number of genes, in RrAa there are 2 genes. So, the number of gametes = 2(2) = 4.

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.
