Unit 5: Heredity

Question 1

Mitosis

Answer 1

-Asexual reproduction
-genetically identical daughter cells (2)
-diploid cells

Question 2

Meiosis

Answer 2

-Sexual reproduction
-genetically different daughter cells (4)
-haploid cells

Question 3

What are gametes?

Answer 3

Sperm and egg cells

Question 4

Crossing over

Answer 4

-During prophase I
-homologus chromosomes exchange genetic material with each other

Question 5

Law of independent assortment

Answer 5

alleles separate independently from each other (randomness)

Question 6

Law of segregation

Answer 6

each haploid recieves one allele from both parents

Question 7

Dominant alleles

Answer 7

expressing trait and creating proteins

Question 8

Recessive alleles

Answer 8

mutations in the gene therefore not producing proteins

Question 9

complete dominance

Answer 9

if dominant alleles is present then dominant trait will be expressed

Question 10

Hybrid cross

Answer 10

genotype ratio 1:2:1
phenotype ration 3:1

Question 11

Dihybrid cross

Answer 11

phenotype ratio 9:3:3:1

Question 12

incomplete dominance

Answer 12

blend of dominant and recessive alleles

Question 13

codominace

Answer 13

both dominant alleles are expressed equally
