Homework Answers
(A) Emirgration
(B) Immigration
The genetic make-up of population canbe influenzed by five factorsand they are:
EMIGRATION: Emigration is the movement of people or individuals out of a population in to another population. This can decrease the population size and growth rate.
IMMIGRATION: Immigration is the movement of people or individuals into a population from other population. This can increases the population size and growth rate.
NATURAL SELECTION: It is the process by which organisms with favourable traits are more likely to produce next generation (reproduce). By reproduction, they pass these traits to their offspring. As time passes these trait helps to adapt to their environment.
MUTATION: It occurs when a DNA is damaged or alteration occurred in the DNA due to a mutagenic substance so that the genetic message carried by the gene is lost. A Mutagen is a substance that can bring about a permanent change to the DNA such that the genetic message is altered.
GENETIC DRIFT: Genetic drift is a change in the frequency of an allele within a population over time.

Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...

The founder effect occurs when a natural disaster kill most of the individuals of a population, living behind a small group of survivors occurs when a new isolated population is founded by a small number of individuals possessing limited genetic variation relative to the larger population from which they have migrated с genetic variation goes down and the frequencies at which different alleles are found in the population, increase D when the number of hetero-zygotes increases and the number of...

When a population is reduced to a very small number of breeding individuals, random genetic changes called occur. As a result of these kinds of changes, variation in genotypes and phenotypes will probably increase compared with the amount of variation present in the original population TRUE OR FALSE? genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced populations TRUE OR FALSE? the reduced population will have a higher probability of extinction than a similar but larger population TRUE OR FALSE?

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...

Suppose we have two species R and S that interact with one another and that we record the change in their populations from year to year. When we begin our study, the populations, measured in thousands, are Ro and So; after k years, the populations are R and S,. If we know the populations in one year, they are determined in the following year by the expressions We will combine the populations in a vector x - and note that...
Consider two genes in a large, randomly mating population of turtles with no movement of individuals...
Consider two genes in a large, randomly mating population of turtles with no movement of individuals in and out of the population and no mutation. The two alleles at one gene, L and M, do not affect fitness. The two alleles at the other gene, T and t, do affect fitness -- they affect the thickness of turtle shells, and the degree to which they are protected from predation. TT individuals have thick shells, which repel predators, and survive best....

Which of the following factors directly affect the size of a population? Note: You can select multiple answers. Birth (number of new individuals born each season). Death (number of individuals who die) Diversity (biological diversity and genetic diversity) Emigration (number of individuals leaving the population) Health (how healthy the members of the population are) Immigration (number of individuals from another population joining the population of interest)
