Question
In a particular breed of flowering plants, two genes on the same chromosome determine flower color and leaf color. For flower color, blue (B) is dominant to pink (b), and for leaf color, white (W) is dominant to green (w). A true-breeding plant with blue flowers and white leaves is crossed with a plant that has pink flowers and green leaves. The offspring are observed and the following phenotypes are tallied. blue flowers and white leaves: 370 plants blue flowers and green leaves: 14 plants pink flowers and white leaves: 12 plants pink flowers and green leaves: 363 plants What is the frequency of recombination between these two genes?
please show your work
Explanation / Answer
The frequency recombination = number of recombination progeny/total number of progeny*100%
= 26/370+363+14+12*100
= 3.4%
