Q

What are the three laws made by Mendel

A

Law of Dominance, Law of Segregation, and Law of Independent Assortment

17
Q

What is the Law of Dominance

A

States that if you possess a dominant “factor” allele it will be expressed in the organism

18
Q

What is the Law of Segregation

A

Parents possess two copies of an allele but give only one to the offspring

19
Q

Law of Independent Assortment

A

Traits are not linked, they assort independently of each other

20
Q

What are the three possible patterns for a Monohybrid cross

A

Homo Dom x Homo Rec
Hetero x Hetero
Hetero x Homo

21
Q

What is the genotype and phenotype of Homo Dom x Homo Rec cross

A

Genotype: 100% Hetero
Phenotype: 100% Dom Trait

22
Q

What is the genotype and phenotype of Hetero x Hetero cross

A

Genotype: 1:2:1 TT, Tt, Tt, and tt
Phenotype: 3:1 Dom to Rec

23
Q

What is the genotype and phenotype of Hetero x Homo Dom cross

A

Genotype: 50% TT, TT, Tt, Tt
Phenotype: 100% All Dom Trait

24
Q

What is the genotype and phenotype of Hetero x Homo Rec cross

A

Genotype: 50% Tt, Tt, tt, tt
Phenotype: 50% (Dom 50%, Rec 50%)
