Question
What is the probability of getting a heterozygous genotypic ratio in a monohybrid cross?
- 25%
- 50%
- 75%
- 100%
Hint:
When the two alleles of a gene are different, it is called heterozygous.
The correct answer is: 50%
- In a monohybrid cross, the parents have homozygous alleles.
- One parent will be dominant and the other will be recessive.
- The F1 generation will be heterozygous
- Self cross of F1 will produce 4 offspring among which one homozygous dominant, one homozygous recessive ad two heterozygous dominant are present.
- Therefore, the probability of heterozygous genotype will be 50%.
