What is one important advantage of using environmental DNA (eDNA), instead of traditional field-based capture
techniques, to study species distributions?
For a given population density, eDNA has a higher probability of detecting a species if it is present.
By looking at telomere length on the chromosomes found in an environmental DNA sample, researchers can gather
information about the age distribution of organisms in a population.
O
By looking at epigenetic marks on an environmental DNA sample, researchers can gather information about the
health of the organisms in a population.
All of the above
In this version of the simulation (500 population size; 500 carrying capacity), all fish are equally likely (though not 100% likely) to survive and reproduce. There are no mutations, nor are there any entering or leaving the population. When they reproduce, they choose a mate from the pool at random and produce ten offspring by chance with the probability of the offspring’s genotypes determined by the punnett square. What caused the allele frequencies to change and vary in the trials? (ex attached).
Please someone can help with some of my biology lab questions. Thank you so much if you can please answer in detailed.

- Posted a picture of my questionarrow_forwardRefer to the figure above. In their investigation of natural selection on Mc1r alleles (the gene that determines coat color) in Arizona pocket mice, Hoekstra et al. determined the frequency of the D and d alleles in each population. They also determined the frequency of alleles for two neutral mitochondrial DNA genes (genes that do not affect and are not linked to coat color). Why did the researchers include the mitochondrial DNA genes as part of their experimental design? Allele change for the neutral mitochondrial genes serves as an experimental group and gives information on any general background genetic difference among these populations. Allele change for the neutral mitochondrial genes serves as a control and determines coat-color differences among these populations. Allele change for the neutral mitochondrial genes serves as an experimental group and gives information on coat-color differences among these populations.
