59) Pedigree analysis is used to study the mode of inheritance of traits in organisms that have long generation time. So, in humans, the patterns of inheritance are studied using pedigree analysis (option c).
60) When a gene is present in x chromosome, but not in Y chromosome, it is an example of sex linkage and studies on x linked inheritance and sex chromosomes provided evidence for pattern of inheritance. The end result of meiosis in animals is four haploid cells. If the gametes if an organism are different morphologically, it is said to be heterogamous. Sister chromatids are formed during the S phase of cell cycle.
