 Answer:
1. genotypically
2. phenotypically
Explanation:
The genotype of an individual represents the total number and types of genes and the alleles of each gene present in the nuclei of its cells. In humans, the presence of two copies of X chromosomes makes an individual female. However, some individuals have two copies of X chromosomes but have masculine features. Similarly, some individuals have one X and one Y chromosomes in their cells. These individuals are genotypically males. But they have some feminine features. This makes them phenotypically female. Phenotype is the morphological expression of genotype.

 DNA synthesis occurs during the S phase, between the G1 and G2 phases of interphase. DNA replication is therefore complete before the mitotic phase begins.
