I have been asked to find the scientific answer for the above 'title' question. I have tried to search on search engines but it does not give me the answer. I hope you will be able to tell me the reason. I have a feeling it is to do with the X and Y chromosome.
Another question which i would like to know the answer is the difference between phenotype and genotype.
Is phenotype the physical characteristics of an organism?
And genotype the inherited characteristics which are found as genes/alleles?
