Genetics: Understanding Monohybrid Cross and Incomplete Dominance
What is the likely ratio resulting from a monohybrid cross with incomplete dominance?
With incomplete dominance, what ratio would you expect to see?
Answer:
A likely ratio resulting from a monohybrid cross with incomplete dominance would be 1:2:1.
In incomplete dominance, the heterozygous genotype produces a phenotype that is intermediate between the two homozygous phenotypes. This means that when two heterozygous individuals are crossed in a monohybrid cross, the resulting offspring would have a genotype ratio of 1:2:1 (1 homozygous dominant, 2 heterozygous, and 1 homozygous recessive) and a phenotype ratio of 1:2:1 (1 dominant phenotype, 2 intermediate phenotypes, and 1 recessive phenotype).
