DRAW OUT CLEARLY each of these chromosomes labeling as appropriate (demoed in class) The cell has a diploid number of 8 Each pair has a set of linked genes that are located on each end of the chromosome (paternal on left, maternal on right) Pair 1 AB and ab Pair 2 DE and de Pair 3 Fg and fG Pair 4 hI and Hi Show what the chromosomes would look like in G1, G2, TI and TII
Q. A eukaryotic cell is diploid and contains 10 chromosomes (5 in each set). In mitosis and meiosis, how many daughter cells will be produced, and how many chromosomes will each one contain?
Task: Show your work/explain your reasoning as much as possible. If a certain species has a DNA content of 12 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a triploid cell (from the same species) in mitotic prophase? Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.

MAKE CONNECTIONS Look at Figure 12.7 and imagine the twodaughter cells undergoing another round of mitosis, yielding four cells.Compare the number of chromosomes in each of those four cells, aftermitosis, with the number in each cell in Figure 13.8, after meiosis. Whatis it about the process of meiosis that accounts for this difference, eventhough meiosis also includes two cell divisions?
HELP URGENTLY!!! NEED RESPONSE FAST Genes A, B and C are on the same chromosome linked in cis (coupling) conformation. A is 13 cM from B, and B is 28 cM from C. The distance between A and C is 41 cM. The coefficient of coincidence is 0.45 for a trihybrid test cross. How many individuals with the genotype aaBbcc do you expect to see among the offspring of the cross if 1000 offspring are obtained? Please show your calculations and round your answer off to the nearest whole number.
URGENT PLZ HELP If you ignore the effect of crossing over, would you expect differences in the genetic information between a spermatid and the secondary spermatocyte from which it was derived? Explain your answer completely.
Using diagrams, illustrate how nondisjunction can result in an aneuploid zygote.
PLEASE ASAP I WILL RATE "Polyploidy is the chromosome increases in the form of multiples of the haploid number.” TRUE OR FALSE
Think about human cells that have 46 chromosomes. Now consider human cells that are undergoing Mitosis vs human cells that are undergoing Meiosis I. Explain very specifically what is lining up at the metaphasic plate in each process (Mitosis vs Meiosis I). (What is lining up, how many, and what is each made of?
MAKE CONNECTIONS The ABO blood type locus hasbeen mapped on chromosome 9. A father who has typeAB blood and a mother who has type O blood have achild with trisomy 9 and type A blood. Using this information, can you tell in which parent the nondisjunctionoccurred? Explain your answer. (See Figures 14.11and 15.13.)
Meiosis stage descriptions 7. homologous pairs line up as tetrads along the middle of the cell 8. one of each homologous pair reaches the ends of the cell, the cell begins pinching in, and two new nuclear membranes form 9. DNA condenses in two haploid cells, the nuclear membranes disintegrate 10. sister chromatids split apart and daughter chromosomes move towards the ends of two cells 11. DNA replication has occured, DNA decondensed in one cell 12. four cells with half of the genetic material of a body cell result, all are different from each other Match the picture or the image with the name of the stage it represents. Use each stage just once for either an image or description.
