Patterns Of Inheretance

Question 1

Define genotype

Answer 1

Genetics constitution of an organism or what alleles it has

Question 2

Define Phenotype

Answer 2

The expression of genes of an organism (what it looks like)

Question 3

Define Codominant

Answer 3

Both alleles are equally dominant and expressed in the phenotype

Question 4

Define sex linkage

Answer 4

A gene whose locus is on the X chromosome

Question 5

Define autosomal linkage

Answer 5

Genes that are located on the same chromosome (not sex linked)

Question 6

Define epistasis

Answer 6

When one gene modifies or masks the expression of a different gene at a different locus

Question 7

What is monohybrid inheritance

Answer 7

Genetic inheritance cross of a characteristic determined by 1 gene

Question 8

What is dihybrid inheritance

Answer 8

Genetic inheritance cross for a characteristic determined by 2 genes

Question 9

How is monohybrid inheritance coded for?

Answer 9

Single letters
UPPER CASE FOR DOMINANT lower case for recessive

Question 10

How are codominant genes coded for?

Answer 10

The gene is a capital letter and the the allele is superscript

Question 11

How is sex linkage inheritance coded for?

Answer 11

The chromosome X or Y is upper case and them the allele is superscript

Question 12

How is autosomal linkage and epistasis coded for?

Answer 12

Single letters lower and upper case
