Anvisha [2.4K]

Answer:

The genotype of the offspring would be heterogeneous.

Explanation:

In four O'clock plants in case of incomplete dominance,  no colour is dominant. They are existing in an intermediate character / a new character. This new colour is pink, not white or red.

The white and red colour flowers are wild type and homogenous type. When the cross occurs and incomplete dominance happen, the F1 flower would be pink one but heterogeneous.

Because according to Mendel's deviation, there are such character appears where neither dominant nor the recessive are the only expressive traits. This has seen in incomplete dominance.

In codominance, which is the another Mendelian deviation, where both the characters has expressed. For example the rose flower having both red and white dots in it. The expression two colours / dominant and recessive characters in the flower is called codominance. Because both expresses at the same time. This codominance genotype is also heterogeneous.
