In snapdragons, red flower color (R) is codominant with white (W), the heterozygotes being pink. The normal (broad) leaves (B) are codominant with narrow (grasslike) leaves (G), the heterozygotes having leaves of medium breadth. If a red-flowered, broad-leaved plant is crossed with a white-flowered, narrow-leaved one, what will be the phenotypes and their expected ratio in the F2 generation?

A mix of both?

Most definitely diluted red (pink)

Irvin Mckay · Answer 2

Pink flower with leaves of medium breadth. The ratio in F2 should be 25% red, 25% white, and 50% pink for color. The ratio for leaves are 25% broad, 25% narrow, and 50% medium breadth.
