| Description: Analysis of a dihybrid cross involving two traits. Each trait is analyzed separately, then the frequencies of each are combined to yield the observed phenotypic ratios, confirming that the genes for these traits assort independently. F1: Smooth Yellow X Smooth Yellow F2: Of all offspring Of all offspring 3/4 are Yellow 3/4 are Smooth < 1I4 are green and if wrinkled 3/4 are Yellow 1/4 are wrinkled < 1/4 are green ©Cengsge Learning. All Rights Reserved. Combined probabilities (3/4)(3/4) = 9/16 Smooth Yellow (3/4)(1/4) = 3/16 Smooth green (1/4)(3/4) = 3/16 wrinkled Yellow (1/4)(1/4) = 1/16 wrinkled green Picture Stats: Views: 161 Filesize: 132.2kB Height: 902 Width: 1500 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=44089 |
