genetics lecture 4

Question 1

Meiosis has two main functions:

Answer 1

1. Produces recombinant chromosomes or a mixture of genetic information from both parental chromosomes
2. Halves the number of chromosomes in a cell (ie production of haploid gametes)

Question 2

If two genes are very close, the probability of crossing over is very low
then what?

Answer 2

Therefore, recombination frequency will be low

Question 3

If two genes are far apart, the probability of crossing over is high
then what

Answer 3

Therefore, recombination frequency will be high

Question 4

what can genetic linkage be used for?

Answer 4

Linkage can be used to map and identify disease genes.
