12.3: Linked genes tend to be inherited together because they are relocated near each other on the same chromosome

Question 1

What was found by Morgan’s new experiment?

Answer 1

with the phenotypes of wings and color, he observed that the genes for the body color and wing size are genetically linked on the same chromosome, they fit the ratio

Question 2

genetic recombination

Answer 2

the production of offspring with combinations of traits that differ from those found in either P generation parent

Question 3

parental type

Answer 3

offspring that match the alleles of the parents

Question 4

recombinant types or recombinants

Answer 4

the other offspring that do not match the alleles of the offspring

Question 5

Over what percent does it tell you the genes are linked?

Answer 5

If the occurrence of the parental type is greater than 50%, the genes are linked

Question 6

genetic map

Answer 6

an ordered list of the genetic loci along a particular chromosome

the further away the genes are, the higher the probability of crossing over is

Question 7

linkage map

Answer 7

defining one map unit as equivalent to 1% recombination frequency, add the 2 frequencies, units equal percent 1 =1

Question 8

map units

Answer 8

defining one map unit as equivalent to 1% recombination frequency
