Answer to Question #108449 in Cell Biology for Judy

Question

In the jimsonweed, purple flowers are dominant to white. When a particular purple flowered jimsonweed is self-fertilized, the progeny are 27 purple-flowered and 10 white flowered progeny(approximately 3:1 ratio). What proportion of the purple flowered progeny will breed true (AA) ? What proportion of the white-flowered progeny will breed true (aa)?

Answer 1

The results of self-fertilazation showed that purple flowers were heterozygous (Aa).

P: Aa x Aa

F1: AA, 2Aa, aa

The proportion of AA to all other genotypes will be 1/4.

The proportion of aa to all other genotypes will be 1/4.
