illustration of relationships and genetic transmission

Question 2

blended expression of both alleles

Question 3

Answer 3

human blood types

3+ alleles

Question 4

Epistatis

Answer 4

one phenotype covers another

Question 5

Sex-linked

Answer 5

genes located on a sex chromosome

Question 6

Answer 6

on the same chromosome

Question 7

automsomes

Answer 7

non sex chromosomes

Question 8

Answer 8

carriers

Question 9

autosomal linkage

Answer 9

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

Question 10

Recombination

Answer 10

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