How many different gamete possibilities could be formed from an organism that has 7 homologous pairs?
If a diploid organism has 8 pairs of homologous chromosomes and one of the 8 pairs is the pair of sex chromosomes. How many total chromosomes does the organism have? How many total autosomes does the organism have? How many chromosomes do gametes of this organism have?
The mosquito, Aedes aegypti, has 3 bivalents (homologous pairs) formed at Meiosis I. How many chromosomes and chromatin strands at present in each of the following steps:
Investigation XI - Meiosis and Gamete Formation Assume an organism has a chromosome number of 6. Further assume that the genes A and a are on two of the chromosomes, B and b on another pair, and C and c on the third pair. Sketch below the arrangements for these chromosomes (1) in a somatic cell such as a skin cell that is undergoing metaphase of mitosis, (2) in a primary spermatocyte in metaphase I and (3) in a secondary...
20. How many cells are formed at the end of Meiosis I & how many copies of chromosomes does each cell have?_ 21. Is DNA copied before Meiosis II? _ 22. How many cells form at the end of Meiosis II and how many chromosomes do they contain? • 23. Oogenesis ultimately gives rise to (one ovum, four ova) with the Chaploid, diploid) number of chromosomes. 24. A sperm cell is a (gamete, zygote), and is (haploid, diploid). 25. When...
A cell undergoing meiosis has four pairs of homologous chromosomes. How many different combinations of maternal and paternal chromosomes are possible within the daughter cells that form? (Do not consider crossing over in your answer.) a.16 b. 8 c. 4 d. 2
Consider an organism that has 2 pairs of homologous chromosomes. Draw one of the cells from this organism as it would appear during late prophase I and during late metaphase I. What would happen to the gametes, if you treated the cell with Taxol, a drug the blocks spindle fiber formation immediately after meiosis I. Assume that the cell is still able to complete cytokinesis. Female armadillos always give birth to four offspring of the same sex. Suggest a mechanism...
