These are the two genes associated with cancer
What is tumor-suppressor and proto-oncogenes

Crossing over occurs during this stage
What is prophase I
300
This is how a test cross works
What is cross a homozygous recessive organism with the organism that has the unknown genotype. If the offspring all display the dominant phenotype, it can be said that the unknown organism is homozygous dominant
300
What is an example of polygenic inheritance
What is height, skin color
300
This is one reason why a dominant allele might not be common in a population
What is heterozygote advantage, individuals do not reach reproductive age, attractiveness/sexual attraction

What is 92
400
This is the law of segregation

400
How can the environment influence genes?
What is tanning, diet, etc.
400
This is an example of a gamete vs. a somatic cell in a human
What is sperm/egg, other cells in the body

Cytokinesis in animal cells involves this, while plant cells has this
What is cleavage furrow and cell plate

Quickly describe meiosis
What is homologous chromosomes join together (synapsis) and cross over. During anaphase I, the homologous chromosomes separate, then, during anaphase II, sister chromatids separate.
