Flashcards in Genetics Deck (16):
1

Law of Segregation

-Genes have alleles
-One allele from each parent
-Alleles separate in meiosis

2

Law of Dominance

-Dominant form vs. Recessive form

3

Law of Independent Assortment

Inheritance of two traits are independent of one another

4

What is the phenotypic ratio expected from a dihybrid cross following Mendelian genetics?

9:3:3:1

5

What will allow genes on same chromosome to be inherited independently?

Crossing over

6

What are the non-Mendelian inheritance patterns?

Incomplete Dominance, Co-Dominance, Sex Linkage, Cytoplasmic Inheritance

7

Cytoplasmic Inheritance

-Mitochondrial DNA
-Plasmids in bacteria

8

Which form of bacterial gene transfer allows for mapping?

Transduction

9

What does an operon consist of?

Operator, Structural genes, Promoter

10

Where does a repressor bind?

Operator

11

Where does RNA polymerase bind?

Promoter

12

In an inducible system, what is the inducer typically?

The substrate for the enzyme being transcribed

13

What forms in an inducible system?

Inducer-repressor complex removes repressor from operator

14

What forms in a repressible system?

Repressor-Corepressor complex

15

What is the corepressor typically?

End products of biosynthetic pathway controlled

16

What are constitutive genes?

Genes always being trancribed/translated
