Question
What is the genotype ratio of the given Punnett diagram?
- 1:1:2
- 2:1:1
- 1:2:1
- 3:1
Hint:
The genotype is the genetic make up of an organism.
The correct answer is: 1:2:1
- Genotype is the genetic make up of an organism.
- Gene is the unit of heredity.
- A gene is made up of two alleles.
- The two alleles can be same (homozygous) or different (heterozygous).
- The given genotypes are AA, Aa, Aa and aa for the offspring.
- Hence, the genotype ratio is 1:2:1
