14. In class we explored how genotype frequencies can change between generations. In our experiment, we started with a population in which every individual was heterozygous for a few traits of interest. The data for the 11 offspring of these heterozygotes are below.

What describes the phenotypic plasticity of an organism best? O the degree of which individuals can change over time by altering their genotype O the effect of variable environment on the genotype of an organism O the variation of the target phenotype for a given genotype in different environments O the change of a phenotype due to ingestion of detrimental plastic material (as for instance plastic straws by sea turtles). O the degree of which a given genotype is adapted to a particular environment
how would you write an hypothesis and prediction from the given data?
p + q = 1 p2 + 2pq + q2 = 1 p is the frequency of the dominant allele q is the frequency of the recessive allele p2 is the frequency of homozygous dominant genotype q2 is the frequency of homozygous recessive genotype 2pq is the frequency of heterozygous genotype Within a population of roses, the color red (R) is dominant over the color white (r). 40% of all the roses are white.a)The percentage of roses in the population that are heterozygous b) The frequency of homozygous dominant individuals =
hi how to figure this one out since it has to associated to all three of them?
Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
The ratio of nonsynonymous differences pernonsynonymous site, dN, to synonymous differences per synonymous site, dS, can be usedto test for positive selection Imagine that in a duplicate pair of loci, oneparalog is evolving neutrally while the other isevolving under strong positive selection. Whatspecific data are needed to detect that situationusing the dN/dS ratio, and what pattern do youexpect to see?
I had trouble with explaining how natural selection affects alllele and genotype frequency. Does natural natural selection affect alleles by causing adaption to happen increasing the frequency of advantageous alleles?

Genetic drift phenotype D. migration |In its absence, allele frequencies in different subpopulations will diverge Source of new alleles entering local population from other subpopulations v The movement of organisms among subpopulations - v Genotypes best suited to survive and reproduce in a particular environment of the offspring | The genotypes that promote survival are favored and contribute disproportionately to the offspring of the next generation known as evolutionary adaptation | The random, undirected changes in allele frequencies, especially in small populations.
1. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution 2. Know that in humans, most of the genetic variation is observed within populations, and know why that is. 3. Know the 4 processes of evolution (3 neutral + natural selection) 4. Know that evolution isn't progressive and doesn't necessarily lead to more complexity 5. Know that evolution can lead to traits that decrease survival (ex: sexual selection)
When artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.
is my work correct? thank you
