Alleles are Different Versions of the Same Gene

Question 1

What do you have most of the time?

Answer 1

Two copies of each gene - one from each parent

Question 2

What happens if the alleys are different?

Answer 2

You have instructions for two different versions (e.g blue and brown eyes) of a characteristic but you only show one version of the two (e.g brown eyes)

Question 3

What is the version of characteristic that appears caused by?

Answer 3

Dominant allele

Question 4

What is the other allele said to be?

Answer 4

Recessive

Question 5

When does the characteristic caused by the recessive allele only appear?

Answer 5

If both alleles are recessive

Question 6

What are letters used to represent in genetic diagrams?

Answer 6

Genes

Question 7

What are dominant alleles always shown with?

Answer 7

Capital letter (e.g C)

Question 8

What are recessive alleles always shown with?

Answer 8

Small letter (e.g c)

Question 9

What does it mean if you’re homozygous for a trait?

Answer 9

You have two alleles the same for the particular gene e.g CC or cc

Question 10

What does it means if your heterozygous for a trait?

Answer 10

You have two different alleles for that particular gene e.g Cc

Question 11

What is your genotype?

Answer 11

The alleles that you have

Question 12

What is your phenotype?

Answer 12

The characteristics the alleles produce
