If a field population started with 50% standard (YY) plants and 50% yellow-green (yy) plants, how would you expect the frequencies of the two alleles (Y and y) to change in future generations? Base this answer on your conclusion in question 3. Note: Exact frequencies are not needed to answer this question, but in relative terms, what changes, if any, do you expect with allele frequencies.

when we obtain a 1: 1 ratio, in which the population is based on plants "Yy" and "yy", it is expected that the allele Y will predominate in number with each generation, in this way it can be predicted that the frequency would change to be of plants "YY" to 90% and 10% of plants "yy", a process called natural selection, so plants with many flowers and leaves will prevail, as well as the highest, becoming a cycle in which the Y allele, due to its characteristics, will become more competitive and successful to reproduce.
