Question

What happens when alleles have incomplete dominance?

Answer 1

Incomplete dominance:

1. An allele is said to be dominant because one copy of that allele makes enough enzymes to supply the cell with a large amount of a given product.
2. When complete dominance occurs, the dominant allele does not completely override the recessive allele and the heterozygous F1 individual exhibits an intermediate phenotype, unlike the parents.
3. Example: When the crossing was done between white-flowered plants with red-flowered plants, the F1 generation obtained had all pink-flowered plants.
