Thanku Which of the following could produce peaks in the electropherogram that are not true alleles? spike stutter pull-up noise all of the aboveYou are a studying the genetic basis of horn color in unicorns. Gene C determines the color of pigment destined for the horn by converting a pink precursor into a purple pigment. C- individuals make purple pigment whereas cc individuals accumulate pink precursor. Gene D ensures the deposition of the pigment into the horn cells, such that D- individuals have a colored horn (purple or pink), whereas dd individuals have a white horn. You breed two purple horned unicorns to each other (CcDd). Assuming Gene C and Gene D are unlinked, what is the probability that the baby unicorn has a purple horn? Please express your answer to 2 decimal places (e.g. 0.69).
- ACTIVITY 4: Multiple alleles and ABO blood groups Karl Landsteiner discovered the ABO blood groups in 1900. He found that glycoproteins called antigens A and B may be found on the surface of human red blood cells. People with type A antigens have blood type A; people with B antigens have blood type B, people with both A and B antigens have blood type AB and people with neither antigen have blood type O. These blood types are important because if a person receives a blood transfusion from someone who has red blood cells with foreign antigens, serious injury or death may result. A person with blood type AB may safely receive blood of which type(s)? ___ A person with blood type A may safely receive blood of which type(s)? __ A person with blood type O may safely receive blood of which type(s)?__ The gene which controls ABO blood type has 3 alleles. Two of the alleles are co-dominant (IA and IB), and the third is recessive (i). What is the genotype of a person…Based on your Figure 3 (i.e. the HF genotype histogram), we would have assumed thatthe increase in the HF genotype would have been consistent (i.e. no variation infrequency) between trials at update 500 due to positive selection using a 0% mutationrate. Why was this not the case? Briefly explain why variation occurred.You observe a population of Japanese 4’oclock plants. These plants can display red, pink or white flowers. Plants with red flowers are homozygous dominant (RR); plants with white flowers are homozygous recessive (rr) and plants with pink flowers are heterozygous (Rr). Based on the following data: 35 plants with red flowers; 25 plants with white flowers; 40 plants with pink flowers. Show all work A) Calculate genotype frequencies of RR; Rr and rr in the population. B) Calculate the allele frequencies of R and r in the population.

Of the corn borer larvae feeding on these Bt crop plants, only 10 percent survive unless they have at least one copy of the dominant resistance allele B that confers resistance to the Bt insecticide. When the farmer first plants Bt corn, the frequency of the B resistance allele in the corn borer population is 0.02. What will be the frequency of the resistance allele after one generation of corn borers have fed on Bt corn?
