Question
Consider two non-homologous chromosomes whose normal sequences of segments and centromere locations are shown here
Chromosome 1 A B C * D E F G H
Chromosome 2 Q R * S T U V
Determine the type (or types) of chromosomal structural changes necessary to produce the following chromosomes
a. S T U V * D E F G H
b. A B V T E D * C
Q R * S F G H
Explanation / Answer
a)
The excange of arms of chromosomes 1 and 2 must take place to obtain the chromosomal sequence
S T U V * D E F G H
b)
Chromosomal inversion deletion must take place to obtain the chromosomal sequence
A B V T E D * C
Chromosomal inversion translocation must take place to obtain the chromosomal sequence
Q R * S F G H
