Step by step
Solved in 2 steps
- A prairie grass species called "little bluestem" is tetraploid. It has four complete sets of chromosomes. There are ten kinds of chromosomes; in other words, each complete set of chromosomes has a total of 10 chromosomes. A single somatic cell (e.g., a cell in a leaf) will have 40 chromosomes, 4 of each kind of chromsome, i.e., 4 of the number 1 chromsome, 4 of the number 2 chromsome, etc. The illustration below shows prophase of meiosis 1 in chromosome number 10. In a diploid cell, there would be one tetrad (group of 4 chromatids) for each kind of chromosome. For example, there would be one tetrad for chromosome 8, one for chromsome 9, etc. When the tetraploid little bluestem undergoes meiosis, how many of chromosome number 10 will each sperm cell carry?Diploid Number of chromosomes, Sex Chromosomes, (+/- whole) Chromosome (+/- partial) e.g. 47, XY, +14 = male with trisomy of chromosome 14 e.g. 46, XX, 1q+ = female with a partial increase to the length of the long arm of chromosome 1 (partial increases or decreases to a single chromosome still have the same diploid number) What is the notation for the following case? A man having Klinefelter syndrome and one Barr body.The duck billed platypus is an unusual mammal. If you examine the sex chromosomes of a female platypus you will find a total of 10 X chromosomes. Examining a male platypus finds 5 X chromosomes and 5 Y chromosomes. No other combinations are seen. Each of these five X chromosomes is unique as is each Y chromosome (i.e. X1 pairs only with X1 or Y1, X2 with X2 or Y2 and so on). Why is this unusual? What unusual event must happen during meiosis in a male platypus? (Think carefully about what happens in meiosis 1)

Which types of cells each have only one set (23)?A phenotypically normal individual has the following combinations of normal and abnormal chromosomes:The normal chromosomes are shown on the left in each pair.Suggest a series of events (breaks, translocations, crossovers, etc.)that may have produced this combination of chromosomes.
- Diploid Number of chromosomes, Sex Chromosomes, (+/- whole) Chromosome (+/- partial) e.g. 47, XY, +14 = male with trisomy of chromosome 14 e.g. 46, XX, 1q+ = female with a partial increase to the length of the long arm of chromosome 1 (partial increases or decreases to a single chromosome still have the same diploid number) What is the notation for the following cases? ( A woman having Turner syndrome.You are an allele on a single uncondensed chromosome in a Yellow fever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6).
