Basics
What type of inheritance pattern does NOT follow simple dominant/recessive Mendelian ratios?
Non-Mendelian inheritance
What blood type is considered the universal donor?
Type O
What determines whether traits are inherited together of separately during meiosis?
Gene location on chromosome
What is incomplete dominance?
Neither allele is completely dominant resulting in a blended phenotype
Type AB
What process can separate linked genes during meiosis?
Crossing over
What type of inheritance occurs when both alleles are fully expressed in the heterozygote?
What blood type shows codominance?
What is the result of crossing over in terms of genetic variation?
New combinations of alleles
What is polygenic inheritance?
What type of pattern describes traits influenced by multiple genes?
What is polygenic inheritance
A single trait being controlled by multiple genes
What does a high recombination frequency between two genes indicate?
They are far apart on the chromosome
What is the chance of a aa offspring from Aa x Aa
25%
What is the typical phenotype pattern seen in polygenic traits?
Continuous variation
What ratio is expected from a dihybrid cross under Mendelian inheritance?
