◉ Metaphase II (Meiosis).
Answer: chromosomes line up at the metaphase plate/equator
◉ Anaphase II (Meiosis).
Answer: -2 cells
-centromeres divide
-chromatids move to opposite poles of the cells
◉ Telophase II and Cytokinesis (Meiosis).
Answer: -goes from 2 cells to 4 cells
-nuclear envelope forms around each set of chromosomes
-cytoplasm divides
◉ Asexual organisms.
Answer: -New alleles must occur independently
-can't be passed around and mixed with the genetic make up/
different alleles of other organisms
, ◉ Sexual organisms.
Answer: -populations can accrue new beneficial alleles in a shorter
period of time than asexual organisms
-organisms in a population can share beneficial alleles
-takes all the best alleles and puts them in a "basket" that selection
can favor
◉ sex creates_____.
Answer: -genetic variation among offspring
-allows populations to adapt to environmental change faster
◉ organisms in more variable environments______.
Answer: -show a higher propensity (a preference) for sexual
reproduction compared to asexual
-could be due to increase in genetic variation to increase rate of
adaptation to the environment
◉ linked alleles/genes.
Answer: -genes are close together on the same chromosome
-breaks the law of independent assortment
-genes closer to each other on a chromosome are less likely to
recombine during crossover
