Question

A plant with yellow flowers was crossed with a plant with red flowers. The F1 progeny obtained had orange flowers. What is the inheritance pattern?​

Answer 1

Mention the characteristics of a true-breeding line.

Answer 2

A plant with yellow flowers was crossed with a plant with red flowers. The F1 progeny obtained had orange flowers. the inheritance pattern obtained is incomplete dominance.

• Incomplete dominance is when a dominant allele, or form of a gene, does not completely cover the effects of a recessive allele.
• it is also called partial dominance.
• Incomplete dominance  occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele.
• the dominant trait of the two flowers is not completely dominant over the recessive trait.

This inheritance in which the traits of both the plants are not accepted individually rather mixed and formed is called incomplete dominance.
