Things Mendel studied.

pea plant 

100
The probability of a heterozygous tongue-rolling parents having a child without the ability to roll his/her tongue.
What is 25%?
100
Allele that masks the effect of another allele.
What is dominant?
100
Heterozygous.
What is a hybrid?
100
The number of chromosomes a gamete will have.
What is half the regular body cell? (half the parent body cell)
200

Explain the law of segregation in regard to the reason alleles split.

The law of segregation basically says that if a creature has a set of alleles, Aa in this case, they are separated during meiosis. Text book definition on Pg.290

200
Letters inside the Punnett square.
What are genotypes of offspring?
200
The study of biology that involves how different traits are transmitted from one generation to the next.
What is genetics?
200
Cross that involves two separate traits.
What is a dihybrid cross?
200
Organisms that can commonly be polyploid.
What are plants?
300

Explain the multiplicity rule

To determine the probability of two things happening at the same time we multiply the probabilities together. Ex: 1/3 x 1/3 = 1/9, coin flip on heads twice? 1/2x1/2 = 1/4 chance.

300
Percentage of heterozygous offspring when 2 heterozygous parent are crossed.
What is 50%?
300
Passing of traits from parents to offspring.
What is heredity?
300
Phenotype.
What is the physical appearance of a trait?
300
Likelihood that a specific event will occur.
What is probability?
400

Explain the concept of epistasis

Epistasis is when a gene at one locus (location) effects the expression of a gene at another. (example: you have a gene that makes your hair blonde, you also have a gene that makes you bald) Pg.281

400
Genotype for pea plant that is heterozygous tall.
What is Tt?
400
Alleles separate during the process of meiosis to create unique gametes.
What is the Law of Segregation?
400
Homozyogous.
What is an organism with two of the same alleles?
400
Different forms of a gene.
What are alleles?
500
Offspring of the P genergation.
What is the F1 generation?
500
Capital letters.
What is the correct way to represent a dominant allele?
500
Inheritance of one trait has no effect on the inheritance of another
What is independent assortment?
500
Cross that involves one pair of contrasting traits.
What is a monohybrid?
500

What is the term used when the offspring of two things has a mix of the two traits? (Ex: Red flower x White flower  = pink flower)

Incomplete dominance
