<span>The gene, is in fact the subunit of information on a chromosome, so this is a true statement. A chromosome is a structure that occurs within cells. It contains the cell's genetic material, which determines how an organism develops. For example, if we are talking about DNA, its molecule is a very long, coiled structure that contains many identifiable subunits known as genes.</span>
The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
Answer:
Explanation:
Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each paternal and maternal chromosome.
The answer is a sudden violent expansion of gas
Do you know what a pangea is well Pangea is another supercontinent the reason why we're not Pangea is because something dead which oceans with lava cools off it cools off from old to new the new rocks are pushing the consonants together and eventually and a couple of million years it will be Pangaea again
