The Daily Grind (Cell Cycle)
This is the longest part of the cell cycle, where a cell spends 90% of its life.
What is Interphase?
During this phase, chromosomes line up right in the middle of the cell.
What is Metaphase?
Unlike mitosis, meiosis results in this many daughter cells.
What is FOUR genetically different daughter cells?
This is the term for having two different alleles, like Aa.
What is Heterozygous?
In this type of inheritance, both traits show up at once (like "co-captains").
What is Codominance?
During the "S" phase of Interphase, this happens to the cell's DNA.
What is It is copied/replicated ?
Mitosis is used by the body for these two main purposes.
What is Growth and Repair?
These are the types of cells (like sperm or egg) created by meiosis.
What are Germ cells or Gametes?
This "Father of Genetics" used pea plants to study heredity.
Who is Gregor Mendel?
This occurs when traits blend together (like red + white = pink).
What is Incomplete Dominance?
These are the names of the two "Gap" phases in Interphase.
What is G1 and G2?
This word describes the final splitting of the cytoplasm.
What is Cytokinesis?
Meiosis daughter cells have exactly this much of the original chromosome count.
What is half (haploid)?
If P is purple and p is white, this is the phenotype of a Pp plant.
What is Purple (the dominant trait always wins)?
This term describes traits that have more than just two allele options (like blood type).
What are Multiple Alleles?
This phase of Interphase is specifically for checking and final prep before Mitosis.
What is G2 (Gap 2)?
In this phase, sister chromatids are pulled away to opposite sides.
What is Anaphase?
Draw the complete steps of Meiosis I on the board. Include Cytokinesis. Include important labels and arrows.
Check board for answer.
This is the genotype of an organism that is "homozygous recessive."
aa (two lowercase letters)
This is the visual tool used to predict the probability of genetic outcomes.
What is a Punnett Square?
Draw a diagram of how the cell cycle is split up into each component. Include the three interphase portions and the two cell divisions portions.
Check answer on board.
Draw a complete flow map of cells going through each phase of PMAT.
Check answer on the board.
Draw the complete steps of Meiosis II on the board. Include Cytokinesis. Include important labels and arrows.
Check board for correct answer.
In a cross of Ff x ff, this is the percentage of offspring that will be grey (F).
50% (The genotypes are 50% Ff and 50% ff)
SpongeBob SquarePants recently met SpongeSusie Roundpants at a dance. SpongeBob is heterozygous (Ss) for his square shape, but SpongeSusie is round (ss). Create a Punnett square to show the possibilities that would result if SpongeBob and SpongeSusie had children. What is the genotypic ratio? What is the phenotypic ratio?
Genotypic ratio = 1:1 (half are Ss, half are ss)
Phenotypic ratio = 1:1 (half are Square shape and half are Round shape)
Check Punnett square on board.
