Question

A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers. This demonstrates a. the mistakes made by Mendel. b. the blending model of genetics. c. a dihybrid cross. d. codominance. e. dominance.

Answer 1

Answer:

Dominance

Explanation:

Purple flowers are dominating character while white flowers are recessive ones. If you have a Punnet's square, you'll see the results as 3:1 where 3 is of purple flowers (2 heterozygous + 1 homozygous) and 1 is of homozygous white flowers. Thereby, seeing dominance.

if there were pink flowers, then it would be the case of co-dominance.

a dihybrid cross is only made when there are 2 characters like pod size and pod colour.

Hope this'll help:)
