Hardy-Weinberg Model Of Genetic Equilibrium Asking the question: If purple bud color is a dominant trait, why do some of the offspring of my purple bud strain have green buds? or I have been selecting Indica mothers and cross-breeding them with Mostly Indica male plants...but I have some Sativa leaves...why? The 1st question reflects a common misconception: The dominant allele will always have the highest frequency. Thats not always the case. A dominant trait will not always spread to the entire population....Nor will a recessive trait always die out. Gene frquencies can occur in high or low ratios regarless of how the allele is expressed. The allele can also change depending on certain conditions. Changes in gene frquencies over time result in different plant characteristics. continued..... |
