Chromosome mutations involve the deletion or duplication of many genes. the effects of chromosome mutations are often much greater than mutations within a single gene, because chromosome mutations a. can only occur at the time of fertilization. b. can cause abnormal development of the offspring. c. are always beneficial to the organism. d. are rarely passed on to the next generation.

Which statement is not an accurate description of meiosis? a) meiosis produces offspring that are genetically diverse. b) meiosis produces offspring that are identical to the parent. c) in sexual reproduction half of the genetic material comes from the father (sperm) and half of the genetic material comes from the mother (egg). d) meiosis decreases the number of chromosomes by half so that when a sperm fertilizes an egg, the resulting zygote has the correct number of chromosomes.
