What kind of trait is dimples?
Hereditary characteristics can be either dominant or recessive, as is the case with humans . Chromosome 5 is thought to be the location of the dominant gene responsible for the inheritance of cheek dimples, while chromosome 16 is thought to be the location of the dominant gene responsible for the inheritance of chin dimples.
It is generally accepted that dimples are caused by a dominant genetic feature, which indicates that the presence of only one mutated copy of a gene in each cell is required to produce the trait. On the other hand, there are academics who argue that there is no evidence to support the theory that dimples are inherited.

is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.
