IBIO 341 Problem Set 3. You are studying a diploid organism (2N = 4) to learn more about mitosis. Gene A is on chromosome 1 and Gene B is on chromosome 2. An individual cell that is heterozygous for both gene A and B is dividing through mitosis. Match each question to its correct value.
Consider three genes L, R, and Q. You want to measure the map distance between these genes. You have at your disposal a dominant and a recessive allele for each of these genes, which you use to perform a three-point cross.
Genetic distances measured with recombination rates are approximately additive: if the distance from gene A to gene B is 15 m.u. and the distance from gene B to gene C is 20 m.u., the distance from gene A to gene C is 35 m.u. A female mouse is heterozygous for the three linked genes described.
The mapper and mapping positions store all positions in Python coordinates, i.e. 0-based. Many users are working with data that is 1-based, such as GenBank or HGVS. Each map position type has a “to_hgvs” and “to_genbank” method for easy conversion.
Genome mapping is similar to solving a big, complicated puzzle with pieces of information collected from laboratories all over the world. Genetic maps p...
The stages of cell division oversee the separation of identical genetic material into two new nuclei, followed by the division of the cytoplasm. Animal cell mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence.
