Basics
Multiple Alleles and Blood types
Chromosomal Inheritance
100

What type of inheritance pattern does NOT follow simple dominant/recessive Mendelian ratios?

Non-Mendelian inheritance

100

What blood type is considered the universal donor?

Type O

100

What determines whether traits are inherited together of separately during meiosis?

Gene location on chromosome

200

What is incomplete dominance?

Neither allele is completely dominant resulting in a blended phenotype

200
What blood type is considered the universal recipient?

Type AB

200

What process can separate linked genes during meiosis?

Crossing over

300

What type of inheritance occurs when both alleles are fully expressed in the heterozygote?

Codominance
300

What blood type shows codominance?

Type AB
300

What is the result of crossing over in terms of genetic variation?

New combinations of alleles

400

What is polygenic inheritance?

What type of pattern describes traits influenced by multiple genes?

400

What is polygenic inheritance

A single trait being controlled by multiple genes

400

What does a high recombination frequency between two genes indicate?

They are far apart on the chromosome

500

What is the chance of a aa offspring from Aa x Aa 

25%

500

What is the typical phenotype pattern seen in polygenic traits?

Continuous variation

500

What ratio is expected from a dihybrid cross under Mendelian inheritance?

9:3:3:1
