Gene Function Analysis in Eukaryotes Flashcards
Who is Gregor Mendel?
Geneticist who discovered the basic principles of hereditary through experiments with pea plants
Why did Mendel use pea plants for his experiments?
Easy to grow, hermaphroditic, lots of inherited variation
Mendel’s First Law
The principle of segregation
Mendel’s Second Law
The principle of independent assortment
When is linkage shown?
When genes are present at different loci but lie on the same chromosome because they don’t independently assort
What is the number of recombinant genotypes in offspring proportional to?
The physical distance between linked genes
What is a genetic screen?
Process that identifies mutations that change gene functions
What is a complementation test?
Tells us whether two mutations with similar phenotypes lien different or the same genes
What did Morgan do?
Drosophila crosses with black and vestigial genes
