Q:make a data chart of 6 organisms. In natural selection allele frequencies change because some alleles confer higher fitness, whereas in genetic drift allele frequencies change because of chance sampling error.

There has been a change in allele frequencies in the population over generations, soby the definition of microevolutionwe can say that the population has evolved. According to the Hardy-Weinberg principle, both the allele and genotype frequencies in a large, random-mating population will remain constant from generation to generation if none of that processes would occur: A) Selection. See Answer Question: Q6.6. Is there a small chance that in sexual reproduction a new allele forms in the offspring that was not present in either of the parents, or are the alleles in the offspring always from at least one of the parents? Instead, populations tend to evolve: the allele frequencies of at least some of their genes change from one generation to the next. The term q2 = the relative frequency of homozygous recessiveindividuals, which corresponds to the ten brown-eyed flies I counted out of 1000 flies sampled. what is the formula for the effective population size N e? is a change in allele frequency as a result of sampling error in small populations, How many alleles will be precent at a loci in a small population after many generations, Graph allele frequency over time if genetic drift is occurring, When genetic drift occurs what happens to the genetic variation within a population, Do the average F(a1) frequency across a 100 populations change over time, no, half of the populations will fix the allele and half will lose it, does the variance in f(a1) across 100 populations change, When genetic drift is happening does is make populations phenotypically more similar to eachother, no because they will fix and lose different alleles at each loci, how does genetic drift operate in lager populations is natural selection is not at play.

All five of the above mechanisms of evolution may act to some extent in any natural population. If we look at just one gene, we check whether the above criteria are true. if the allele frequency does not change over time then: it is likely that the allele does not offer any fitness advantage and the population is large. In Sal's example, all of the organisms in the population get an equal opportunity to mate. How would one how do ways organisms reproduce affect the frequency of genes appearing? Honey bee are of three types adult bees: workers, drones, and a queen. If gametes from a gene pool combine randomly to make only a small number of zygotes, the allele frequencies among the zygotes may be different than they were in the gene pool because: A. 1. Would there still be homozygous fish? a. only recessive traits are scored. (choose one from below) 1. the effects of natural selection are more pronounced in small populations 2.changed in allele frequencies over many generations are inevitable with sexual reproduction 3. alleles combine more randomly with a small number of zygotes 4. the effects of sampling error are more pronounced with smaller samples. I was perplexed by this but then realized that I think the author must be using a narrow definition of "non random." In crossing a homozygous recessive individual with a heterozygote, what is the chance of getting an offspring with the homozygous recessive phenotype?
