If the measured allele frequency differs from the expected value,what does it indicate?

If $51\%$ of the members in a population possess at least one recessive allele,find the frequency of the dominant phenotype.

If the values of the mean and median for a specific trait in a population are equal,what is the most likely outcome?

In the Hardy-Weinberg equation,the frequency of heterozygous individuals is represented by:

In which of the following conditions does the gene frequency remain constant in a population?

According to the Hardy-Weinberg principle,allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It makes several assumptions which are given below:
$i.$ Random Mating
$ii.$ Sexual Reproduction
$iii.$ Non-overlapping Generations
$iv.$ Occurrence of Natural Selection
$v.$ Small size of population
Identify two assumptions which do not meet the criteria for a population to reach Hardy-Weinberg Equilibrium.
