INCOMPLETE DOMINANCE
Answer: INCOMPLETE DOMINANCE - It is also called partial dominance . when the neither allele of parents is completely dominant over the other. It is recognised by the heterozygous condition expressing an intermediate phenotype relative to the parental phenotypes.

What will the punnet square look likearrow_forwardThe image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…arrow_forward

Three individual plants were collected from nature (thus not necessarily pure breeding) before flow- ering and were either crossed or self-pollinated. The results are shown below.
