Contains 1 set of chromosomes

Question 2

Diploid

Answer 2

Contains 2 sets of chromosomes

Question 3

Autosomes

Answer 3

Homologous to each other, has the same shape and length, contains the same set of genes, in the same order, even though not necessarily having the same allele

Question 4

Genotype

Answer 4

Combination of alleles possessed by the organism

Question 5

Phenotype

Answer 5

Observable traits of an organism that can result from the interaction between the genotype and the environment

Question 6

Dominant

Answer 6

Can affect phenotype in both homozygous and heterozygous individuals

Question 7

Recessive

Answer 7

Only affects the phenotype in homozygous recessive individuals

Question 8

Phenotypic Plasticity

Answer 8

The ability of a single genotype to produce different phenotypes in response to different environmental conditions

Question 9

Incomplete Dominance

Answer 9

Where no allele can mask over each other in heterozygous form

Question 10

Test Cross

Answer 10

Test for the presence of recessive alleles in the organism - TT or Tt x tt

Question 11

Codominance

Answer 11

Both alleles can affect the phenotype equally in heterozygote

Question 12

Continuous Variation

Answer 12

Trait that is controlled by a number of genes
