B19 Monohybrid Inheritance

Question 1

Genotype

Answer 1

the genetic makeup of an organism in terms of the alleles present (e.g Tt or GG)

Question 2

Homozygous

Answer 2

having 2 identical alleles of a particular gene (e.g TT or gg)

Question 3

Heterozygous

Answer 3

having 2 different alleles of a particular gene (e.g Tt or Gg), not pure-breeding

Question 4

Dominant allele

Answer 4

an allele that is expressed if it is present (e.g T or G)

Question 5

Recessesive allele

Answer 5

an allele that is only expressed when there is no dominant allele of the gene present (e.g t or g)

Question 6

Phenotype

Answer 6

the physical or other features of an organism due to both its genotypes and its environment (e.g tall plant, green seed)
