Summary Introduction
Introduction:
A mutation is defined as an abnormality in the gene expression that can cause alteration in the number and thestructure of chromosomes. A full chromosomal set of an individual is known as karyotype. Abnormality in the number of chromosomes in an individual is referred to as aneuploidy. It can be of different types, such as, trisomy, monosomy, tetrasomy, and many more.

What is a haplotype?a. A species with one set of chromosomesb. A cell with one set of chromosomesc. The linkage of alleles or molecular markers on a chromosomed. All of the above describe a haplotype.
A research scientist is studying diseases associated with homologous chromosomes and notices that the same gene along the chromosome has different function what can you conclude about his findings?
A.
The homologous pairs have been recombined and therefore he is studying end joining of chromosomes
B.
He is studying sex chromosomes and the differences are because the chromosomes are from a male species organism
C.
He has identified different alleles among homologous chromosomes.
D.
He is studying basic chromosome remodeling during fertilzation
