Genetics

Question 1

An allele that is expressed no matter what the other allele is:

Answer 1

Dominant

Question 2

An allele that is expressed only if you inherit two of that allele:

Answer 2

Recessive

Question 3

Offspring or kids of parents:

Answer 3

F1 generation

Question 4

Grandkids of original parents:

Answer 4

F2 generation

Question 5

Egg or sperm cell formed as result of meiosis, haploid:

Answer 5

Gamete

Question 6

Has 2 copies of the same allele for a given trait:

Answer 6

Homozygous

Question 7

Has different alleles for any given trait:

Answer 7

Heterozygous

Question 8

Neither allele is dominant, offspring are a blend (red flowers x blue flowers = purple flowers):

Answer 8

Incomplete dominance

Question 9

A trait is controlled by more than one gene. The more dominant the allele, the severity in color etc is.

Answer 9

Polygenic

Question 10

A single gene controls more than one character. If one dominant gene is present, dominant trait is expressed for all characters:

Answer 10

Pleiotrophy

Question 11

Equal probability of each allele being produced in meiosis (50/50):

Answer 11

Law of segregation

Question 12

Heterozygous x homozygous produces what proportion:

Answer 12

9:3:3:1

Question 13

Neither allele is dominant, but alleles are expressed ex. red flowers x white flowers = red and white flowers)

Answer 13

codominance

Question 14

Neither allele is dominant, but alleles are expressed (ex. red flowers x white flowers = red and white flowers)

Answer 14

codominance
