Question 1

Dominant

Answer 1

Trait that is expressed

Question 2

Recessive

Answer 2

Trait which is only expressed if there are no dominant alleles present

Question 3

Allele

Answer 3

Gene that is found on the exact same place on a chromosome

Question 4

Genotype

Answer 4

All the different variants that could be present in a given organism.

Question 5

Phenotype

Answer 5

Traits that are physically observable.

Question 6

Co-dominance

Answer 6

When both unique alleles are present and form a mix of both traits

Question 7

Mendel’s three laws

Answer 7

Law of dominance, segregation and independent assortment

Question 8

Homozygous recessive

Answer 8

Both alleles are recessive (eg. ee)

Question 9

Answer 9

Both alleles are dominant (eg. EE)

Question 10

Heterozygeous

Answer 10

One dominant allele and one recessive allele is present, but dominant allele is expressed (eg. Ee)

Question 11

Dihybrid cross

Answer 11

Two traits that are being observed in any given organism

Question 12

Monohybrid cross

Answer 12

A single trait that is being observed in any given organism

Question 13

Sex linked traits

Answer 13

Traits that are specifically found on the sex chromosome (number 23)

Question 14

Incomplete dominance

Answer 14

Two alleles that don’t completely conceal each other (eg. red+white flowers will make a pink flower in incomplete dominance.)
