geographic isolation and reproductive isolation

Phase 1: Starts with the separation between populations. Separated populations become adapted to local conditions and become genetically differentiated over time.

Phase 2: Genetic isolation is completed, reproductive isolation develops mostly in the forms of prezygotic RIMs.

What is the relationship between the rate at which molten material cools and a minerals crystals
worty [1.4K]

The answer is; The slower the cooling the larger the crystals

Slow cooling allows the aqueous molecules of the compound to find a perfect geometry and grow into a large crystal. Fast cooling causes impurities to be incorporated into the growing lattice hence atagonizing the growing crystals.

Answer:

1. fragmentation- genetically identical

2. budding- genetically identical

3. haploid cells from two different mycelia fuse to form a zygote- genetically distinct

4. one hyphae creates spores through mitosis- genetically identical

Explanation:

1) Fragmentation is a form of asexual reproduction i.e. one parent, employed by certain organisms including fungi in which a FRAGMENT breaks off from the single parent to produce new cells. Since it is an asexual reproduction, the resulting cells will be GENETICALLY IDENTICAL.

2) Budding is another form of asexual reproduction that fungi undergoes e.g yeast. In the budding process, buds develop on the parent cell and later grow into mature cells that are GENETICALLY IDENTICAL to the parent cell.

3) In fungi, two different mycelia can produce haploid sex cells via the process of meiosis, which then fuse to produce a ZYGOTE. This method is a sexual means of reproduction. Hence, the zygote formed will be GENETICALLY DISTINCT from the parent.

4) Hyphae (threadlike filaments) of a fungi can via MITOTIC DIVISION produce spores, which then germinates under favorable conditions and grows into a new fungus. This new fungus cell is GENETICALLY IDENTICAL to the parent hyphae.
