A chromosomes has the following segments, where  represents the centromere: M N O  P Q R S T Give the chromosome sequences that would result from the following mutations: a. Deletion of MN b. Pericentric inversion of NOP c. Inversion of RS, followed by tandem duplication of QRST

a. O | | PQRST

b. MP | | ONQRST

c. MNO | | PQSRTQRST

Explanation:

Deletion of MN: this refers to the removal of the MN segment from the seuence. thus we will have:

MNO | | PQRST - O | | PQRST

Pericentric inversion of NOP: this is a type of chromosomal rearrangement in which the order of sequence of changed through a 180 degrees orientation and this involves the centromere. thus, we will have

MNO | | PQRST - MP | | ONQRST

Inversion of RS: this does not include the centromere and is called a paracentric inversion.

MNO | | PQRST - MNO | | PQSRT

then followed by tandem duplication of QRST. Thus we will have:

MNO | | PQSRTQRST

chordata is the answer

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
