Please help :) Which of the following is true about chromosomes? a. more complex animals have more chromosomes b. chromosomes are found in many places of the cell. c. sperm and eggs have half the chromosomes as other cells. d. some chromosomes do not have DNA in them.
In humans, there are 46 chromosomes in a body cell. A process called meiosis makes sure that when a gamete is made, the sperm or the egg cell each only has 23 chromosomes, half of the original number, so that when they join to form a zygote when fertilization occurs, the zygote will have a total of 46 chromosomes, like every cell in a human does. So the answer is 23. Depending on the species of the organism, however, the number of chromosomes in a gamete will vary.
C should be correct. Here are the reasons why the others cannot be correct. a-The complexity of an organism dos not depend on the number of chromosomes, if mollies fish and humans are considered. b-chromosomes are only found in the nucleus. d-chromosomes are composed of DNA and protein in any case.
