Mendelian Inheritance 2

Question 1

Genotype

Answer 1

• the genetic composition of an individual, especially in terms of the alleles for particular genes

Question 2

Phenotype

Answer 2

• the observable traits of an organism

Question 3

Two factor crosses

Answer 3

• a cross which an experimenter follows the outcome of two different traits

Question 4

Mendel’s Law of Independent Assortment

Answer 4

• two different genes randomly assort their alleles during the process that gives rise to gametes

Question 5

Chromosome theory of inheritance

Answer 5

• theory that inheritance patterns of traits can be explained by the transmission patterns of chromosomes during meiosis and fertilization

Question 6

Pedigree analysis

Answer 6

• genetic analysis using info contained within family trees
• the aim is to determine the type of inheritance pattern that a gene follows

Question 7

The product rule

Answer 7

• the probability that two or more independent events will occur is equal to the products of their individual probabilities

Question 8

Binomial expansion equation variables

Answer 8

P= [(n!)/x!(n-x)!] multiplied by p^x *q^n-x

P = probability that the unordered combo occurs
n= total # of outcomes
x= # of outcomes in one category(ex. blue eyes)
p= individual probability of x
q= individual probability of the other category (ex. brown eyes)

!–> factorial, product of integers from “n” down to 1

Question 9

Binomial expansion definition

Answer 9

• an equation used to solve genetic problems involving two types of unordered events

Question 10

Age of onset

Answer 10

• time of life at which symptoms of a genetic disease appear

Question 11

Simple Mendelian Inheritance

Answer 11

• an inheritance pattern of a single gene that exists in alleles that exhibit a simple, dominant/recessive relationship and products observed ratios in the offspring that readily obey Mendel’s Laws

Question 12

Autosomal

Answer 12

Referring to a gene that is located on a chromosome that is not a sex chromosome
