Final answer:
In Experiment 14.2, without selective pressure, the Red and Blue Allele frequencies would likely remain unchanged due to the Hardy-Weinberg equilibrium. With selective pressure, the Red Allele's frequency could increase or decrease depending on whether it is advantageous or not. Heterozygous advantage or genetic drift can also affect allele frequencies.
Step-by-step explanation:
In Experiment 14.2, in the absence of selective pressure, the frequencies of the Red Allele and Blue Allele would most likely have remained unchanged after 10 generations. This is because, in a stable environment without selective pressures, allele frequencies in a population are expected to remain constant according to the Hardy-Weinberg equilibrium.
When selective pressure is introduced, the frequency of the Red Allele after 10 generations would likely increase if it is advantageous, or decrease if it is disadvantageous. The presence of selective pressures can lead to the preferential survival and reproduction of organisms with beneficial alleles, thus changing allele frequencies over time.
If heterozygous individuals are favored by natural selection, the frequencies of alleles A and a could change to reflect the advantage of heterozygosity. Genetic drift can also play a role, particularly in small populations, leading to random fluctuations in allele frequencies.
