- A normal diploid cell from a chimpanzee has 48 chromosomes. How many chromosomes will be in a chimpanzee cell just before meiosis begins, after meiosis I, and after meiosis II? After which of these stages will the chromosomes have two chromatids?arrow_forwardHuman somatic cells have 46 chromosomes. How many chromosomes are present in human cells undergoing each of the following phases of meiosis?

The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. There are no other chromosomes. Using diagrams, show a cell at metaphase of mitosis and show the results of mitosis. Ensure you show the location of the gene loci on the different chromosomes.arrow_forward
- At what stage of mitosis can the kind and number of chromosomes be easily detected and determined? How does non disjunction in meiosis lead to numerical chromosomal aberration? If cell division during gametogenesis is non meoitic, what is its consequence to the future generations of diploid organisms? What is the relationship between meiosis and fertilization?arrow_forwardA sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?arrow_forwardDuring metaphase I of meiosis, tetrads align along the metaphase plate independently of each other. Therefore, there is a random “shuffle” of maternal and paternal chromosomes in the resulting gametes.The following diagram demonstrates how this works in a diploid cell with four chromosomes (2n=4) . Because there are two pairs of chromosomes and each pair can align in one of two ways during metaphase I, the number of possible variations in the gametes produced is 22 or 4.For an organism that is , there are three pairs of chromosomes, so the number of possible variations in the gametes produced due to independent assortment in metaphase I is 23 or 8. In an organism with a haploid number of 7, how many possible combinations of maternal and paternal chromosomes can occur in its gametes? a. 72=49 b. 27=128 c.17=1 d. 214=16 384arrow_forward

Assume a single nondisjunction event involving the X chromosome occurs in a cell undergoing mitosis in a human female. First, consider the daughter cell with the smaller number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have?
