A normal chromosome A B C D * E F G H I J K has mutated toA B C F E * D G H I J K J K.This is an example of a _________________ chromosomal mutation. ( * denotes the centromere)
Group of answer choices
Pericentric inversion of DEF and tandem duplication of JK.
Pericentric inversion of DEF and displaced duplication of JK
Paracentic inversion of DEF and displaced duplication of JK.
Paracentric inversion of DEF and tandem duplication of JK.
Consider the following "pericentric" ("around the center") inversion. In one an individual, a simplified 8-gene sequence along one chromosome is 1234
5678 while a pericentric inversion occurred on their other homologous
chromosome, resulting in the sequence 1265 4378 (the dot represents the centromere). Draw these homologous chromosomes lined up (as during crossing over, in Prophase l). If a crossover event occurred between gene locus 3 and 4 (slicing between them) on the original chromosome, what would the crossover products look like? What would be the "problem" with each of the chromosomes that result?
An initial crossover event will occur between A and B, as indicated in the corresponding image. After this initial event occurs, a second cross over event occurs (not illustrated) involving the products of the first crossover event. Given the chromosome organization below, which two chromatids of the bivalent were involved and between which genes did the second crossover event occur to produce the indicated chromosomes?
a. A B c, A b c, a B C, and a b C
b. A B C, A B C, a b c, and a b c (return to the original crossover depicted in the image, and then determine how the second crossover event produced this arrangement
