Select all that apply Question options: abc ABC aBc ABc abC aBC Abc AbC View question 1 feedback Question 2, , 1 / 1 point Nondisjunction during meiosis I will result in ________. Question options: n n-1 n+1 n+1 and n-1 n, n-1, and n+1 View question 2 feedback Question 3, , 1 / 1 point Combination of alleles that independently assort is usually higher than the number of chromosomes because Question options: jumping genes translocation segregation gene linkage crossing over View question 3 feedback Question 4, , 1 / 1 point A karyogram that contains 23 pairs of chromosomes with a different pair for the 23rd pair would describe a(n) Question options: autosomal pair male female disorder View question 4 feedback Question 5, , 1 / 1 point The most common time individual assortment occurs is when genes are ________? Question options: unlinked linked close together on non-sister chromatids of homologues View question 5 feedback Question 6, , 1 / 1 point Your study partner is confused. “I thought Watson and Crick discovered genes – who are all these other people?” Help out by matching each discovery with the scientist(s) who made it. __3__, Genes nearby on a chromosomes are linked, but can become unlinked by recombination. ________ __2__, Genes are carried on chromosomes. ________ __4__, DNA has a double helical structure. ________ __1__, Traits arise from discrete units that remain unchanged even when not exhibited. ________ __5__, Developed a technique for predicting the outcome of crosses. ________ 1., Mendel 2., Sutton and Boveri 3., Morgan 4., Watson and Crick 5., Punnett View question 6 feedback Question 7, , 1 / 1 point What is the difference between a karyotype and a karyogram? Question options: Karyotypes and karyograms are terms that are used interchangeably to describe chromosome mapping Karyotypes describe the number of chromosomes and what they look like (size bands and centromere placement). Karyograms is the study of the whole set of chromosomes arranged in pairs by size, and position of the centromere Karyograms describe the number of chromosomes and what they look like (size bands and centromere placement). Karyotypes is the study of the whole set of chromosomes arranged in pairs by size, and position of the centromere Karyotypes are unstained chromosomes in interphase or prophase. Karyograms are stained chromosomes from metaphase View question 7 feedback Question 8, , 1 / 1 point Why do so many geneticists focus on studying yeast, fruit flies, nematodes, mice or the small plant Arabidopsis? Question options: These pest organisms result in millions of dollars of damage and hurt the economy. They are ideal for modeling human disease since they have all the same organs. They have multiple features that allow for cheap, fast and efficient manipulation of genes and chromosomes. They are some of the few organisms in which mutations can be generated. View question 8 feedback Question 9, , 1 / 1 point Serious disease syndromes are associated with trisomy of chromosome 21 (Down syndrome), 18 (Edwards syndrome) and 13 (Patau syndrome). What is the result of trisomy of the other chromosomes? Question options: no disease symptoms minor disease symptoms disease symptoms with varying severity based on genetic background lethal early in development View question 9 feedback Question 10, , 1 / 1 point Which is likely to disrupt the function of the most genes: a 500kb deletion, a 500kb inversion, or a 500kb translocation? Question options: Deletion Inversion Translocation
