In a hypothetical plant assume that the color of the flower is under the control of a single gene Assume that the gene has two alleles the dominant allele R that corresponds to the color red and the recessive allele r that corresponds to the color yellow R Red r yellow Someone gifted you a plant with a red flower but you do not know for certain whether such plant is homozygous or heterozygous Rex Br CBS RE Br Br C RR x rr r 1 What type of cross should you perform to determine whether the plant is homozygous or heterozygous it is Heterozygous 2 You counted three offspring all with red flowers from the cross in question 1 You then concluded that your plant must be homozygous Two questions a Write a Punnett square that justifies such conclusion b What is the probability that your conclusion is WRONG i e your plant is instead heterozygous 3 Assume again that all offspring of the cross in question 1 are all red and that you conclude again that your plant must be homozygous How many offspring should you count to ensure that the probability of your conclusion being wrong is less than 0 001 i e you have less than 0 1 chance of being wrong

Genetic drift resulting from a disaster that drastically reduces population size is called natural selection gene flow the bottleneck effect the founder effect

Broccoli cabbages and Brussels sprouts all descend from the same wild mustard and can still interbreed These varieties were produced by genetic drift artificial selection O natural selection mutation

The ultimate source of all new alleles related to evolution is chromosomal duplication natural selection genetic drift mutation

A rabbit population consists of animals that are either very dark on top or very light on top The color pattern is not related to sex No rabbit shows intermediate coloration medium darkness This pattern might result from O stabilizing selection sexual selection disruptive selection O directional selection

A population can be defined as Individual Population Community Ecosystem all individuals of a species regardless of location or time period in which they live a group of individuals of different species living in the same place at the same time a group of individuals of a species plus all of the other species with which they interact a group of individuals of the same species that live in the same area and interbreed

Which of the following statements best describes the true nature of natural selection The strong eliminate the weak in the race for survival Heritable traits that promote reproduction become more frequent in a population from one generation to the next Organisms change by random chance Only the strongest survive

Mate attracting features such as the bright plumage of a male peacock result from Ointrasexual selection O intersexual selection O disruptive selection O stabilizing selection

To study motor function on microtubules scientists can create purified stable fluorescently labeled microtubules and motors different colors and watch movement of the kinesin walking along the microtubule using a fluorescence microscopy This allows scientists to analyze the kinetics of kinesin movement velocity of movement what regulates movement etc A How might you expect that molecular biologists create stable and labeled microtubules for this experiment B Based on what you know about how kinesin motor activity is regulated by ATP ADP and nucleotide release what do you think would happen if you added only ADP to this rather than ATR12
