What does PMAT stand for?
Prophase, Metaphase, Anaphase, Telophase
100
What is a genotype vs phenotype?
Genotype: set of certain letters to show trait
Phenotype: observable characteristics
100
Provide three environmental examples that can alter protein performance
Light, pH, temperature, nutrition, UV, radiation
100
What's the difference between linked and unlinked genes?
Linked: Genes close together on the same chromosome
Unlinked: Genes on different chromosomes or genes far apart on the same chromosome

Teenager gets water-bending chosen by the local puddle to return a glowing green rock to an angry glowing rock monster after a tattooed man-child loses his magic fishhook.
Moana

Explain cytokenesis
Division of cytoplasm and formation of new daughter cells
200
What is the difference between homozygous and heterozygous?
Having the same/different gene on homologous chromosomes
200
Define proportionate heritiability
Organisms phenotype can be entirely due to the environment
200
What is a test cross?
Method used to find the hidden genetic makeup (genotype) of an organism that shows a dominant physical trait (phenotype).
Cross the mystery organism with a pure-breeding recessive organism to see what traits the offspring show.

An uncle kills a child's father, so a pig and a big rat help him get revenge
The Lion King
300
What stage of meiosis does crossing over occur?
Prophase l
300
What is imcomplete dominance?
Neither allele is fully expressed resulting in the blending of both alleles
300
What 3 factors influence phenotype?
Genetics, environment, epigenetics
300
What acronym is used to expand genotypes into gametes and what does it stand for?
FOIL: First, outside, inside, last

Women with untreated anxiety accidentally invent inclement weather and gaslights her sister about it
Frozen
400
What is the final outcome of meiosis compared to mitosis?
Meiosis: 2 identical somatic cells
Mitosis: 4 genetically different gamete cells
400
What is blood types (ABO) an example of?
Codominance
400
What are the two epigenetic modifications?
DNA methylation and histone modification
400
Explain recombinant gametes
Reproductive cells that contain a new combination of alleles not found in the parent's original chromosomes. This happens through genetic recombination during meiosis, when homologous chromosomes exchange pieces of DNA via crossing over or independent assortment

The forgotten one meets the red-haired one, and suddenly the distinction between a physical threat and a psychological one becomes rather inconvenient
Spiderman: Brand New Day
500
Why is crossing over and independent assortment good for genetic diversity?
Forms new recombinant chromatids and randomly line up along the metaphase plate
500
Why is colour blindness and Haemophilia A more common in males?
Located on the X chromosome and males only have 1 X chromosome, nothing to counteract it
500
Why is epigenetics important?
Control cell differentiation and provide a mechanism for developing organisms to respond to their environment
500
What two inheritance patterns are these pedigrees?
1. Y-Linked
2. Autosomal Dominant
