Mitosis
What happens during G2 phase?
When does genetic variation occur?
Prophase
What kind of cell has a cell wall?
Plant
What are somatic cells?
Body cells
Distinguish between dominant and recessive traits
Dominant traits block another genetic factor and recessive traits are blocked by dominant traits and appear when two recessive genetic factors are present
Anaphase
4 haploid cells
What are the four macromolecules?
Lipids, proteins, carbohydrates, and nucleic acids
What are sister chromatids?
Two identical copies of a single chromosome joined together by a centromere
What are the three kinds of mutations?
Insertion, deletion, and substitution
Which phase takes the longest during mitosis?
Interphase
Why is meiosis important?
Reproduction
What is the function of the golgi apparatus?
To transport proteins in and out of the cell
What is a phenotype?
A trait that can be seen or observed
What is the difference between incomplete dominance and codominance?
Incomplete dominance is the blending of two dominant traits. Codominance is the mixing of two traits where both dominant traits are still visible.
What are the three sub phases in Interphase?
G1, S, and G2
In what phase does the nuclear envelope reappear?
Telophase
What is the cell theory?
All living things are made up of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells
What is cytokinesis?
The division of the cytoplasm
What's the difference between genetics and heredity?
Heredity is the passing of traits from parents to offspring and genetics is the study of how traits are passed down
Why is mitosis important?
Cell repair, growth, and replacement
Mr. and Mrs. Bright are having a baby. How many chromosomes will the baby get from each parent?
23 chromosomes from each parent = 46 chromosomes in total
Which organelle makes the proteins?
Ribosomes
What's the difference between homozygous and heterozygous?
Homozygous - two alleles of a gene are the same (bb) heterozygous - two alleles of a gene are different (Bb)
Mr. and Mrs. Bright are having a baby but want to know the phenotype of their child. Mr. Bright is homozygous recessive (d) for dimples and Mrs. Bright is heterozygous. What is the probability their child will have dimples?
