Flashcards in Bio 141 Notes (4/17/14) Deck (10):
1

Pedigrees

illustration of relationships and genetic transmission

2

Incomplete dominance

blended expression of both alleles

3

Codominance

human blood types
3+ alleles

4

Epistatis

one phenotype covers another

5

Sex-linked

genes located on a sex chromosome

6

linked genes

on the same chromosome

7

automsomes

non sex chromosomes

8

females can be ________ for sex-linked traits

carriers

9

autosomal linkage

aka genetic linkage
independent assortment doesn't work
linked genes are physically joined on he same chromosome
inheriting one allele affects the inheritance of allele at different genetic locus

10

Recombination

- alleles from linked genes may end up on different chromosomes by crossing over
- 'map units'
- crossing over is more likely over larger distances
