a)Karyotype is a test to examine chromosomes in a sample of cell . where as Karyokinesis is the division of nucleus to daughter cell .
b)Autosomes differ from sex chromosomes, which make up the 23rd pair of chromosomes in all normal human cells and come in two forms, called X and Y. Autosomes control the inheritance of all an organism's characteristics except the sex-linked ones, which are controlled by the sex chromosomes.
c)While individual organisms bear different alleles (for example Rr) are called heterozygous. A homozygous trait is when the same kind of two alleles associate to form a trait. ... The homologous pairs of chromosomes consist of either same alleles (both black or brown) or different alleles (black and brown).
