Match All the Diagnostic Features That May Apply to That

Question 50

Matching

Match all the diagnostic features that may apply to that aberration. Note that each diagnostic feature may be used more than once.

Premises:
deletion
duplication
inversion
translocation
Responses:
formation of chromosomal “cruciform” structures in meiosis I
formation of chromosomal “loop” structures in meiosis I
Recombinant frequencies between genes on the same chromosome are (much) lower than expected.
reduced fertility (other than semisterility)
semisterility
pseudodominance
pseudolinkage (two genes on separate chromosomes do not segregate independently).

Recombinant frequencies between genes on the same chromosome are (much) lower than expected.
