Question

When a heterozygous genotype results in a phenotype that is intermediate between the two homozygous conditions, this type of inheritance is referred to as A: incomplete dominance B: codominance C: polygenic D: complete dominance.

Answer 1

Incomplete dominance

Step-by-step explanation:

• If an heterozygous genotype has an intermediate phenotype then this type of inheritance is called incomplete dominance.
• For eg in case of Antirrhinum majus the flower with homozygous dominant alleles is red in color and the flower with homozygous recessive allele in white in color but in heterozygous condition the flower colour is pink .
• Here on gene is not completely dominant over other and hence results in an intermediate phenotype.
• We should keep in mind that dominance depends upon the gene product , phenotype from this product and upon the phenotype that we choose to examine .
