A normal chromosome and its homolog carrying an inversion are given. the dot (•) represents the centromere. normal: a b c • d e
kotegsom [21]

The type of inversion is Paracentric inversion.

There are two types of inversion at the chromosome level, depending on the centromere:

Paracentric inversions:

the centromere is not included in the inversion.

Pericentric inversions:

The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.

the structure that will form during synapsis is inversion loop.

These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.

QUESTION 31 Chipmunk mitochondrial DNA was fingerprinted using the single primer amplified region technique (SPAR) and the PCR r
natima [27]

Answer:

It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)

Explanation:

The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
