Inheritance Flashcards
1
Q
Gregor Medel
A
He..
2
Q
Mendelian Laws:
A
- Male & Female contribute equally to inheritance (diplioid)
- Traits can dissapear across generation
There are versions of each factor (Allele) - Traits can dissapear across generations(dominants versus recessive
3
Q
Gametes are
A
Haploid
4
Q
WHen are alleles seperated?
A
When haploid gametes form
5
Q
REMEMBER Mendels Laws:
A
- Law of independent Assortment- seperation of alelles for one gene occurs independently of the seperation of alelles for any other given gene(they happen randomly)
- Law of segregation- alelles are seperated when haploid gametes form
- Principle of dominance- recessive alleles will be masked by dominant alleles
6
Q
What is genotype
A
Aa, AA, aa
7
Q
Phenotype
A
The physically expressed trait
8
Q
What is sex linkage
A
sex-linked because their expression and inheritance patterns differ between males and females.
9
Q
Polymerase chain reaction
A
1: Denaturation, heat seperated strands (no helicase)
2: Annealing, primers designate copying sequence
3: Elongation, Taq polymerase copies the sequence
10
Q
Why do we want to amplify DNA sequences?
A
For eq. at crime scene you want to get more copies of the DNA
11
Q
What is the aim of gel electrophoresis?
A
To seperate proteins or fragments of DNA according to size
