What is the gene frequency of recessive gene q….?
Hope this helps-Fruit acidity as such appears to be gouverned by a single major gene, low acidity being a recessive character. The additional genetic variation is explainable by the additive gene action model. This mode of inheritance causes the pH distribution of seedlings in progenies to shift with a higher mid-parent pH towards more low-acid *** sweet (pH 3.8) and fewer high-acid *** sour (pH 2.9) seedlings or vice versa with a lower midparent pH. As a result, in crosses between heterozygotes (Mama) the total proportion of undesirable seedlings -low plus high-acid ones-, remains similar, irrespective of the mid-parent pH. This proportion constituted about one third of the seedlings. A same proportion, but of mainly sour plants, was found in crosses between relatively acid homozygotes (Mama) or between these and similar heterozygotes. It was less than one quarter if the heterozygous partner was medium-acid and a few percentages only when both the homozygous and heterozygous partner w
