Answer:When two different diseases strike a population, the genotype frequencies may be affected depending on various factors such as the mode of inheritance of the diseases, the frequencies of the disease alleles in the population, and the interaction between the diseases.
In some cases, the genotype frequencies may remain unchanged if the diseases do not interact with each other or if the diseases have independent modes of inheritance. However, if the diseases interact or if they have overlapping genetic factors, the genotype frequencies may deviate from the expected frequencies based on the individual disease frequencies. This can result in changes in the prevalence of certain genotypes in the population, potentially leading to changes in disease outcomes and population dynamics. The specific impact on genotype frequencies would depend on the complex interactions between the diseases and other factors in the population.
