Please solve A group of iguanas living on a beach have substantial variation in their scale thickness phenotype andthis characteristic is heritable. A tsunami hits the beach and kills a large number of the iguanas. After thetsunami, the proportion of thin scaled iguanas in the population is significantly higher than before thetsunami. Scale thickness is not associated with ability to survive a tsunami. Select the answer that bestdescribes how this population will change from generation to generation assuming that the survivors ofthe tsunami reproduce.This population will evolve from generation to generation and will not be better adapted to its environmentas a result.This population will experience random change but will not evolve from generation to generation.This population will experience evolution by natural selection from generation to generation because of thetsunami.This population will experience random change from generation to generation and will be better adapted toits environment as a result.

Evolution in biology can be mostly simply described as descent with modifications, which comprises…

Answer the following question briefly and explain it correctly ( The question is all about Mechanisms that Produce Change in Populations ). Observe the two pictures and Recognize the SIMILARITIES and the DIFFERENCES between individuals or animals belonging to the same species .
Which statement describes a difference between sample standard deviation (SD) and the standard error of the mean (SEM)? OSD measures how data points differ from the sample mean. SEM measures how the sample mean differs from the population mean. OSD describes a unitless value but SEM has the same units as the data. The value of SD is always smaller than the value of SEM for any sample population. O Studies that include more sample measurements have lower values of SD. SEM does not change when the sample size increases.
Color in Mclver beetles is determined by two alleles at one gene locus. Mclver beetles must have a heterzygous genotype (genotype A1A2) in order to have a brown color phenotype. Calculate the frequency of the brown beetles in the population if the frequency of the A1 allele is 0.1.
There are 653 individuals in a population 104 of the rabbits in the said population have recessive floppy ears and 549 rabbits have dominant short ears. Use this information to calculate The dominant allele frequency the recessive allele frequency the homozygous dominant frequency the heterozygous frequency and the homozygous recessive frequency
In a population of 300 snakes, a certain gene has two alleles, A and a. The frequency of allele a is 0.3. What is the expected number of individuals of genotype AA in this population? Group of answer choices 210 147 90 180 128
Brown fur helps unicorns blend into their environment better than white fur. Therefore, brown furred unicorns are more likely to survive predators and hunters compared to white furred unicorns. If fur colour is a heritable trait, how would the population change over time? Describe how the proportion of individuals with brown versus white fur would change over time, if at all. What process is occurring in the population?
A difference in survival and reproduction among members of a population that vary in one or more traits is called ________.
Explain below term is true or not ? "Proportion of total phenotypic variation in a population thatis due to genetic factors"
Choose the answer below that is true of gene flow. all of these none of these gene flow makes populations more similar gene flow may introduce new alleles into a population gene flow almost certainly alters allele frequencies
Construct an example of a phenotype distributioncurve for a population under directional selection that isincreasing in body size.
A researcher studies two types of fly populations. Population A have stubby bristles which are both shorter and blunter than population B. This is because the flies are homozygous for a certain allele for the stubble gene which affects bristle length. These flies are ebony coloured with black bodies. This is because they are homozygous for a certain allele for the ebony gene that affects body colour. Population B have longer and tapered bristles than population A and are not stubbly in appearance. This is due to them being homozygous for a different allele for the gene that affects bristle length to population A. These flys are not ebony coloured and have brown bodies. This is due to them being homozygous for the gene that affects body colour. The researcher crosses parental flys (P1) from population A with those from population B and counts the number of offspring that have stubble and non-stubble bristles, and the number of offspring that are ebony-coloured and non-ebony-coloured…
Please answer this question correctly: True or False: The traits of individuals who survive the longest spread through the population.
