During the gap 1 stage of the cell cycle, a cell does _________________.
How would you describe cytokinesis?
The processes of mitosis and cytokinesis produce two identical is known as ________________.
The process of organizing and condensing DNA into its compact form takes place at the start of
________________.
During which phase of mitosis do sister chromatids separate from each other?
Which of the following statements is true of cytokinesis?
How many chromosomes are in a human gamete?
How would you describe the genetic material a person receives from his or her father?
How would you describe the process of meiosis?
What are homologous chromosomes?
Describe meiosis I.
What happens to sister chromatids in meiosis II?
Give an example of a biological trait.
When Mendel crossed plants that were purebred purple-flowered with plants that were purebred
white-flowered, the resulting offspring all had purple flowers. When allowed to self-pollinate,
this F generation gave rise to white-flowered plants as well as purple. As a result, Mendel
determined that individual traits are ________________.
Mendel was able to identify predictable patterns of heredity. He succeeded mainly because he
chose to study traits that ________________.
Hair color and eye color are examples of a person's ________________.
When an organism has two alleles at a particular locus that are different, the organism is called
________________.
If a pea plant were homozygous recessive for height, how would its alleles be represented?
An allele is dominant in a heterozygote when it is ________________.
What do the letters inside the grid of a Punnett square represent?
What is the probability that the offspring of a cross between a homozygous recessive parent and a
heterozygous parent will be homozygous recessive?
The term for a cross that involves just one trait, such as pod shape, is called a
________________.
What is the phenotypic ratio of a monohybrid cross between two heterozygous parents?
What was Mendel’s observation with dihybrid crosses?
Describe crossing over.
During what stage of meiosis does crossing over occur?
