Select all that apply. Beetles from two geographically isolated populations are captured and brought to the lab. When an adult male from one population and an adult female from the other population are placed together, they mate, and the female lay eggs a couple of days later. The eggs hatch, the beetles develop into adults but are sterile. Which of the following are true? Sexual selection is likely responsible. Dobzhanski-Muller genetic incompatibility is likely responsible. This is an example of post-zygotic reproductive isolation. This is an example of pre-zygotic reproductive isolation.

Which of the following are true of adaptive radiations? OAdaptive radiations involve relatively rapid speciation. The evolution of the Hawaiian silverswords is an example of an adaptive radiation. OAdaptive radiations can occur when an ancestral species colonizes a new arca and adapts to multiple open niches. Question 4 What are the three major steps of…
the area titled Genotype Relative Fitness. Notice that the default is for all three genotypes to be set at 1.0. This indicates that all three genotypes have the same effect on survival and reproduction. Change the Genotype Relative Fitness of the rr genotype to 0.6. This indicates that the rr genotype (white phenotype) has a strong disadvantage over the other type genotypes in terms of survival and reproduction. Start the simulation and let it run for 200 generations. http://virtualbiologylab.org/ModelsHTML5/PopGenFishbowl/PopGenFishbowl.html When you started the simulation, your initial alleles frequencies were: R = 0.5 r = 0.5 What are your allele frequencies after 200 generations of strong selection?
Two Manx cats mate. Manx allele is dominant but is lethal in homozygous individuals. What is the probability that the first three offspring will display the wild-type phenotype (non-Manx)? Show your work including a Punnett square.
Matching Terms: Match the term from the list at right that is best described by the following statements. An allele that determines an organism's appearance. A. Phenotype Organisms in which self-fertilization produces offspring all identical to the B. Genotype parent. C. Allele Allele pairs of an inherited character separate from each other during the D. Homozygous production of gametes (egg and sperm). E. Heterozygous An organism's observable traits. F. Dominant An organism that has two different alleles for a gene. G. Recessive An allele that requires two copies to have a noticeable effect on an H. Monohybrid organism's phenotype. I. Dihybrid An alternate version of a gene. J. Law of segregation A cross between two individuals that are heterozygous for one character. K. Law of independent Alleles of a gene segregate independently of other pairs of alleles during assortment gamete formation. L. True-breeding An organism that has two identical alleles for a gene.

Two Manx cats mate. Manx allele is dominant but is lethal in homozygous individual. what is the probability that any two of six total offspring will display the wild-type phenotype (non-Manx)
Applying Hardy-Weinberg equilibrium. For instance, a trait is caused by the homozygous state of a gene that is recessive and autosomal. 9% of individuals are expressing the phenotype. What is the percentage of individuals that are heterozygous?
Below you will find a spreadsheet of the "class" data, use this to complete data table 2. Remember, the class is a total of 24 students, to calculate frequency use the genotype with the highest frequency for each characteristic and divide that number by 24.

ipie nelIX them. QUESTION 3 Nondisjunction is rare. Which of the following is FALSE? O A. Nondisjunction is when chromosomes separate properly in meiosis. O B. Nondisjunction is when homologous or daughter chromosomes stick together and move to the same pole. O C. Nondisjunction results in some eggs or sperm with too many chromosomes and some with too few chromosomes. O D. In humans, eggs and sperm made from nondisjunction can have 22 or 24 chromosomes, instead of the normal 23. Click Save and Submit to save and submit. Click Save All Answers to save all answers. Save.

From the same population of dragons. Two alleles B and encoding for phenotypes blue and purple scales, P is dominant over B. You have a population of 345 individuals. PP = 100; BP = 90 , and BB = 145 . What is the frequency of the B allele? Please use and round to four decimal points.
Recessive epistasis: In a cross between fruit flies that are both double heterozygous for modifier gene and coat color, in the total offspring of 192, how many fruit flies have gray- coat, white coat, and black coat? A recessive allele blocks the expression of the coat color of fruit flies. Make a null hypothesis, compute for chi-square and determine if the null hypothesis is accepted or rejected.Show your answer, table, punnet square, and solution.
