Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
7) Chromosome I from your mother and chromosome I from your father are said to be homologous. This is because the chromosomes: A) appear the same size in a karyotype. B) have different genes on them. C) have the same genes on them. D) determine the sex of the child. 8) Why do karyotypes always show chromosomes at the point when cell division is about to occur? A) This is the only cell cycle point in which the chromosomes are unduplicated. B) The...

Question 2: The Atlas blue butterfly has 224 homologous pairs of chromosomes. Each pair consists of one chromosome from the butterfly's mother and one from its father. A. Assuming no crossing over, what is the probability that a sperm this butterfly makes has all of the chromosomes from the butterfly's own father? Why? (You do not need to calculate out this number- a number with an exponent is fine.) (roughly 3-4 sentences) B. How many chromosome 17's does this butterfly...
