Recombination Flashcards
1
Q
What is the result of double crossover on test crosses?
A
They can make alleles end up on the same original chromosome resulting in them look like they are not linked
2
Q
What is a three point test cross?
A
Order of 3 genes is established in a single set of progeny.
3
Q
Why are three-point test crosses conducted?
A
This method allows for double crossovers to be detected and provides more accurate map distances.
4
Q
How close is recombination percentage to the actual physical distance?
A
Recombination percentage underestimates map distance after 20%
