Match the type of chromosomal mutation with the correct description

Question 4 options:

	tetrasomy
	monosomy
	trisomy
	allopolyploid
	inversion
	autopolyploid
	nullisomy
	translocation

1.	missing both memebers of a homologous pair of chromosomes
2.	missing a single chromosome
3.	having an extra chromosome
4.	gaining a homologous pair of chromosomes
5.	having extra complete sets of chromosomes all coming from the same species
6.	having more than two complete sets of chromosomes where the sets come from different species
7.	chromosome segment's orientation is changed so that the piece that was closest to one end of the chromosome is now closest to the other end
8.	switching of pieces of chromosomes between non homologous chromosomes

Expert Solution

Answer =

Tetrasomy = gaining a homologous pair of chromosomes.

Monosomy = Missing a single chromosome

Trisomy =Having an extra chromosome.

allopolyploid =Having more than two complete sets of chromosomes where the sets come from different species.

inversion =chromosome segment orientation is changed so that the piece that was closest to one end of the chromosome is now closest to the other end.

autoployploid =having extra complete sets of chromosomes all coming from the same species.

nullisomy =missing both members of chromosomes.

translocation = switching of pieces of chromosomes between non homologous chromosomes

Explanation = there are different types chromosomal mutations are present:

monosomy - is a condition in which there is missing of a single chromosome.

example - cri-du-chat syndrome is caused by monosomy of chromosome 5.

Tetrasomy - presence of four copies , instead of the normal two.

trisomy - Having an extra chromosome.example -down syndrome caused by extra 21 chromosome.

nullisomy - a type of mutation in which there is missing of pair of homologous chromosomes.

inversion = is rearrangement in which a segment of chromosome is reversed end to end.

translocation - is type of mutation in which part of chromosome is transferred to another chromosome.
