- Which statement about the relationship between genetic map and physical map is FALSE? The correlation between Genetic map distance and Physical map distance is not absolute. Roughly speaking, for two genes on the same chromosome, the bigger their genetic map distance is, the bigger the physical map distance is. The genetic map is in a way a distorted picture of the physical map. 1 genetic map unit (1cM) always correlates with a certain distance on the physical chromosome.arrow_forwardWhat is independent assortment? Does independent assortment occur during mitosis or during meiosis?arrow_forwardWhat is a genetic interval?arrow_forward
- Describe the following (50 words minimum per concept): chromosomes, genes, alleles and traits and explain how they are related.arrow_forward*If two genes are linked on a chromosome and over 50 map units apart, in theory you will not recover more than 50% recombinants, which is the same as independent assortment (genes on two different chromosomes). Using diagrams, show why this is so.arrow_forwardWhat is heterosis? Discuss whether it is caused by a single geneor several genes. Discuss the two major hypotheses proposedto explain heterosis. Which do you think is more likely to becorrect?arrow_forward
- Genes exist in pairs in individuals; during the production of gametes, the pairs are separated so that a gamete has only one of each kind. This is known as which of the following? Group of answer choices A-mitosis B-the principle of segregation C-nondisjunction D-recombination E-principle of independent assortmentarrow_forwardExplain pedigree analysis?arrow_forwardA cytogeneticist has collected tissue samples from members of a certain butterfly species. Some of the butterflies were located in Canada, and others were found in Mexico. Through karyotyping, the cytogeneticist discovered that chromosome 5 of the Canadian butterflies has a large inversion compared with chromosome 5 of the Mexican butterflies. The Canadian butterflies were inversion homozygotes, whereas the Mexican butterflies had two normal copies of chromosome 5. 1) Would a cross between Mexican and Canadian butterflies produce phenotypically normal offspring? and 2) Would the offspring of the cross (so F2 generation) be fertile?arrow_forward
- A botanist carries out a cross pollination with two red poppies. In the result he obtained 75% red flowers and 25% white flowers. Determine the genotypes of the parents, using the letter R.arrow_forwardFind the probability that the offspring is AA. Find the probability that the offspring is aa. What is the probability that the offspring of a heterozygous parent is homozygous? What is the probability that the offspring of a heterozygous parent is heterozygous? How does this compare with the result in the absence of mutation?arrow_forwardWhat are overlapping genes?arrow_forward
