Genetics

Question 1

Incomplete Dominance

Answer 1

Both alleles (different versions of the same gene) are EXPRESSED AS A BLEND in the heterozygote

Question 2

Codominance

Answer 2

Alleles (different versions of the same gene) are SIMULTANEOUSLY EXPRESSED in the heterozygote

Question 3

X-linked:
Recessive:

Answer 3

More common in males as they only have 1 x chromosome: 1 allele = has the trait

Question 4

X-linked:
Dominant:

Answer 4

Trait is common in pedigree
Males & females equally affected
Affected father pass it to ALL daughters

Question 5

Y-linked:

Answer 5

trait occurs in males only
reoccurs in all sons of affected males
daughters of affected men= phenotypically normal & do not have affected offspring

Question 6

Sexual Reproduction

Answer 6

2 parents
Fusion of female & male cells (gametes)
Parent & offspring are NOT identical
Slower
Variation

Question 7

Asexual Reproduction

Answer 7

1 parent
No gametes produced
Parent & offspring are identical
Faster
Less/no variation
