Question 12

Four concepts in mendel’s model

Answer 12

Alternative version of genes, for each character- two alleles, two alleles differ, law of segregation

Question 13

Inherited characters / traits

Answer 13

Alleles

Question 14

Represented twice

Answer 14

Genetic locus

Question 15

Determine’s organism’s appearance

Answer 15

Dominant allele

Question 16

No noticeable effect on organism’s appearance

Answer 16

Recessive allele

Question 17

Law of segregation

Answer 17

2 alleles separate during gamete formation and end up in different gametes

Answer 18

Homozygous

Question 19

Has a pair of alleles that are different

Answer 19

Heterozygous

Question 20

Answer 21

Genotype

Question 22

Mendel derived law of segregation by following a single trait

Answer 22

Law of independent assortment

Question 23

Illustrates inheritance of two characters

Answer 23

Dihybrid cross

Govern mendelian inheritance

Answer 24

Laws of probability

Occurs when phenotypes of heterozygote and dominant homozygote are same

Answer 25

Complete dominance

Question 26

Two dominant alleles affect phenotype in separate distinguishable ways

Answer 26

Codominance ex: human bloodgroup MN

Question 27

Phenotype of F1 is between phenotypes of two parental varieties

Answer 27

Incomplete dominance (red + white = pink)
