Question 1

Diploid

Answer 1

• two sets of chromosomes (2n)

Question 2

Homozygous

Answer 2

• identical alleles for the same gene on homologous chromosomes

Question 3

Heterozygous

Answer 3

• different alleles for the same gene on homologous chromosomes

Question 4

Dominant allele

Answer 4

• a gene that masks the ffect of a recessive allele
• masks only the same gene on a homologous chromosome

Question 5

Recessive Allele

Answer 5

• gene that is masked by a dominant allele

Question 6

Complete Dominance

Answer 6

• only the dominant allele from the genotype of a heterozygous individual is expressed

Question 7

Phenotype

Answer 7

• physica characteristics that you can see and can be altered by the environment

Question 8

Genotype

Answer 8

• the genetic composition located on a particular gene locus
• represented using letter symbols

Question 9

Co-Dominance

Answer 9

• Both alleles (white or red) are expressed equally.

Question 10

Incomplete Dominance

Answer 10

• neither allele are expressed but are instead a mix of each other (red and white = pink)

Question 11
