What do mitosis and meiosis have in common?
Both start with diploid cells.
Both promote genetic variation.
Both occur in unicellular organisms.
Both produce identical daughter cells.
Which best describes the end result of meiosis?
two diploid cells identical to the parent cell
four haploid cells identical to the parent cell
two diploid cells different from the parent cell
four haploid cells different from the parent cell
During which actions can an exchange of genetic information occur during meiosis, rather than during mitosis?
assortment and alignment
alignment and crossing over
crossing over and replication
assortment and crossing over
Which best describes the purpose of sexual reproduction?
to produce offspring that are non-viable
to produce offspring that are genetically identical
to produce offspring that exhibit greater genetic variations
to produce offspring that are genetically identical to their parents
Which is true in both mitosis and meiosis?
production of haploid cells
division of two cells into four
cytokinesis after nuclear division
formation of genetically identical cells
Which is the most likely reason for an individual to be born with 45 autosomes and 2 sex chromosomes?
crossing-over of one of the homologous chromosome pairs during the process of mitosis
crossing-over of one of the homologous chromosome pairs during the process of meiosis
nondisjunction of one of the homologous chromosome pairs during the process of mitosis
nondisjunction of one of the homologous chromosome pairs during the process of meiosis
Why is approximately 50% of any individual’s DNA inherited from that individual’s father?
It was passed to the individual by a gamete from the father.
It was passed to the individual by a somatic cell from the father
Half of the individual’s cells descend from the father’s gamete.
Half of the individual’s nuclei descend from the nucleus of the father’s gamete.
What is a result of crossing over during meiosis?
genetic variation
extra chromosomes formed
loss of chromosomes
production of gametes
An individual has three number 21 chromosomes. Which is most likely the cause?
disjunction
crossing over
gene mutation
nondisjunction
Meiosis produces cells in the haploid state. In which process is the chromosome number restored to the diploid state?
ovulation
fertilization
nondisjunction
spermatogenesis
