A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessivefor the trait). For the following questions, assume that the population fits the parameters of the Hardy-Weinberg law. What is the frequency of the recessive allele?

Explanation:

Hardy Weinberg law is represented by the equation below

p² + 2pq + q² and states that the frequency of alleles and genotypes will remain constant in the absence of evolutionary disturbances such mutation, natural selection, migration and the population is large and mating is random.

where p² represent the frequency of homozygous dominant geotypes and 2pq represent the frequency of heterozygous genotypes and q² represent the frequency of the homozygous genotypes

p is the frequency of the dominant alleles and q is the frequency of the recessive alleles.

given

q² = 25% = 0.25

q = √0.25 = 0.5

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
