Textbook Question
Chapter 10.2, Problem 4CC
WHAT IF? A certain eukaryote lives as a unicellular organism, but during environmental stress, it produces gametes. The gametes fuse, and the resulting zygote undergoes meiosis, generating new single cells. What type of organism could this be?

| The Role of Meiosis
Key Idea: There are two types of cell division in eukaryotes,
mitosis and meiosis, but only meiosis produces cells that are
genetically different to the parent cell.
New cells are formed when existing cells divide. There are
two forms of cell division in eukaryotes, mitosis and meiosis.
Mitosis produces two identical daughter cells from a parent
cell. Meiosis is a special type of cell division, and produces
sex cells (gametes or spores) for sexual reproduction. In
sexual reproduction, sex cells from two parents combine to
form an individual that is genetically different to its parents.
The sex cells in humans, called eggs and
sperm, are produced by meiosis. Events
occurring during meiosis creates gametes
with unique combinations of gene variants
and so creates genetic variability.
Sexual reproduction rearranges and
reshuffles the genetic material into new
combinations. This is why family members
may look similar, but they'll never be
identical (except for…
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 fill in pleasearrow_forward1. Meiosis practice with ascospores The life cycle of the fungus Sordaria fimicola begins in the haploid state. After two different types of strains combine, they develop a diploid nucleus. As the life cycle continues, the diploid nucleus undergoes meiosis (2 cell divisions, remember?) followed by mitosis (a trick the fungi do to make more mileage out of the mating). This produces eight haploid ascospores which are stored in a sac called an ascus. The spores line up in a way that shows these cell divisions. After the spores have matured, the sac will burst, allowing the ascospores to be released. These spores are haploid and thus begin the life cycle again. Sordaria fimicola is often used to observe crossing over because the wild type strain has black ascospores and the mutant type has tan ascospores. When a combination of the two strains go through meiosis, the location of the ascospores will directly show if crossing over has occurred. The below pictures shows a fruiting body with…arrow_forwardPlz asaparrow_forward
