WebFixation occurs when one allele becomes the only allele for a gene in a population, meaning that all other alleles for that gene have been lost. This statement is true. Fixation is when the frequency of one allele is one hundred percent for a population. As a result, all individuals will be homozygous for that particular gene. ... WebBiology.

Schwartz located a mutation in a gene called Adh1, which when homozygous causes maize to be unable to produce alcohol dehydrogenase. Schwartz then subjected seeds, with both normal alcohol dehydrogenase activity and no activity, to flooding conditions and observed whether the seeds were able to germinate or not. He found … crypto with paypal
