Answer:
ummmmmm??? oooooook??????
Species evolve over time based on their environment.
If part of a group of a species gets isolated into a new environment, then both species (the initial environment and the new one) will evolve differently because of their different environments and in result become different.
So since they both evolve differently based on their different surroundings, the group that was isolated becomes a new species.
Answer:
Explanation:
In the members of the class ascomycetes such as yeast, two haploid yeast cells of two different stains or mating types fuse to form a diploid zygote. Zygote quickly undergoes meiosis or reductional division to form four haploid spores called a tetrad. The tetrad is contained in a sac-like structure called an ascus or fruiting body. Formation of ascus is the characteristic feature of ascomycetes. In the ascus tetrad are not arranged in any specific order. The tetrad are called random or unordered spores. The genetic analysis of the genotypes in the tetrad can tell us about the events during meiosis.
