Bio II - Ch. 8

asexual reproduction A single individual is reproducing.

meiosis Meiosis produces haploid gametes from a diploid parental cell.

23 This is the number of chromosomes in a single set of human chromosomes. Normal human gametes carry 23 chromosomes.

C and D Once meiosis I is completed, cells are haploid.

16 16 is half of 32. A diploid organism whose somatic (nonsex) cells each contain 32 chromosomes produces gametes containing 16 chromosomes.

can produce great variation among the offspring As long as there is some genetic variation in the parents, different offspring will inherit unique combinations of genes from each parent, creating variation among offspring. Asexual and sexual reproduction differ in that sexual reproduction can produce great variation among the offspring.

genetically identical offspring Asexual reproduction produces genetically identical offspring. During asexual reproduction, yeast cells can produce genetically identical offspring.

binary fission Binary fission is the method used by bacteria to divide. Bacteria divide by binary fission.

DNA replication The DNA must be copied in order to proceed. The first step of bacterial replication is DNA replication.

All of the above are appropriate answers: - the amount of DNA present - whether the DNA is housed in a nucleus or not - whether the DNA is linear or circular

distribution of a copy of the single parental chromosome to each daughter cell Prokaryotes reproduce by a type of cell division called binary fission, which involves replicating the single chromosome and distributing the copies equally to two daughter cells. In bacterial cells, binary fission involves distribution of a copy of the single parental chromosome to each daughter cell.

It ensures that each daughter cell receives one copy of the chromosome. The separation of the duplicating chromosomes ensures that each daughter cell receives a chromosome.

prokaryotes Prokaryotes (such as bacteria) reproduce by a type of cell division called binary fission. The term binary fission is best applied to prokaryotes.

The sequences are identical. Except for the occurrence of rare mutations, this is always the case. Both sister chromatids come from replication of a single DNA molecule, which is present in the one chromatid before replication.

before it is about to divide This ensures that genetic material can be appropriately distributed to each of the daughter cells. A cell replicates its entire chromosomal DNA only before it is about to divide.
