With the mapping of the human genome and the development of karyotypes to predict genetic abnormalities, there is a growing need for researchers in the field of a) medicine. b) animal behavior. c) genetic counseling. d) environmental science.

Option C, genetic counseling

Explanation:

Genetic research has given a better clarity to the researcher regarding genetic diseases and various genetic abnormalities based on the arrangement of chromosomes (as visible in karyotype analysis). Thus in any karyotype analysis the inheritable nature of diseases is determined through counseling. Through genetic counseling,  further mating's that could lead to appearance of any certain abnormality can be removed. Basically, a Karyotyping is done at the metaphase of cell cycle therefore the overall prediction is based on the complete set of metaphase chromosome.

Hence, more research is to be done on genetic counselling part to analyse the karyotype report perfectly

Option C is correct
