Chromosomes and Genetics Name 1. Edward and Jenna had 4 children together. They have a few "interesting" traits, shall we say! Look at the chromosome combinations that each child received and list their genotype and phenotype. Key: D= long eyelashes B = brown eyes F= freckles G = vampire teeth T= tall W = werewolf fur d = short eyelashes b = red eyes f= no freckles g = no vampire teeth t = short w = no werewolf fur
Copyright 2006 Nature Publishing Group Nature Reviews | Genetics Copyright © 2006 Nature Publishing Group Nature Reviews | Genetics The microscope image above shows the human chromosomes from a white blood cell. To create the image, researchers put cells in culture under conditions that encourage the cells to divide. They bathed the cells in a hypotonic (low salt) solution, which caused the cells to swell until their plasma membrane burst open. They "squashed" the chromosomes to spread them out, and stained them with a dye to make them visible under the microscope. Human chromosomes are numbered from longest (1) to shortest (22) plus the sex chromosomes X and Y. In the image chromosome 1 is about 7 micrometers. Answer the following questions. 1) What word(s) in the description above indicates that the chromosomes are not from a cell undergoing meiosis? 2) Based on the size, shape and appearance of the chromosomes in the image, in what cell cycle stage was the cell that the chromosomes…
Figure 1. Showing a homologous pair of chromosomes that carry two linked genes. Here we can see that one chromosome carries A and Balleles, while the other homologous chromosome carries a and b alleles. This is much more informative than just giving the genotype of AaBb. Another way to symbolize the arrangement of alleles on a chromosome is to give the symbols for alleles on one chromosome above a horizontal line, and the symbols for the alleles on the homologous chromosome below the horizontal line. For example: A Figure 2. Showing the arrangement of alleles for a pair of linked genes. Here we can see that, exactly like the example in Figure 1, one chromosome carries A and B alleles, while the other chromosome carries a and b alleles. 1. Suppose that Gene G and Gene D are linked. If the genotype of an organism is GGDD, use both types of symbols you learned in Figure 1 and Figure 2 above to show the arrangement of alleles for this organism.
Identify the chromosomes in the spread based on their size and banding pattern. Arrange them as shown in the organized picture. I have this image that I have no idea how to start! I get what I'm looking at but I'm having trouble determine if my order is right! Please help me. I've attached the spread of the chromosomes and an example of how they should look.

Question - http://bluehawk.monmouth.edu/~bio/karyotypes.htm Pick from the list of abnormal karyotypes and arrange the chromosomes in a karyotype. Use the "print screen" button to copy your finished karyotype onto a word processing document. For "Diagnosis" write the chromosome set that has the abnormality, and what type of abnormality it is.
