Flashcards in Pedigree shiz Deck (13):
1

Define genome

total genomic material of cell or organism

2

Define gene

DNA sequence encoding functional molecules (mRNAs, tRNAs etc)

3

Define allele

variant of a gene

4

Define multiple allelism

gene has many alleles in the population

5

Wild allele

Most frequent allele of a gene in population

6

Locus

position of a gene in chromosome

7

Genotype

the alleles that make up genetic constitution

8

Complex (compound) heterozygote

person with 2 different mutant alleles

9

Homozygote? Heterozygote?

Homo --> person with 2 identical alleles
Heter --> person with 2 different alleles

10

Hemizygote

person carries only single copy of gene

11

Phenotype

observable expression of genotype

12

Phenotypes: Define:
Dominant? Recessive? Codominant?

Dom = expressed even in heterozygote form
Rec = expressed only in homozygote form
Codominant = both alleles expressed

13

List the types of mendelian or monogenic inheritance

- Auto. dom
- auto recess
- X linked dom
- x linked rec
- mitchondrial
- y linked
