Here is a summary of the data.

Calix
More Information:
• The mass of an X chromosome is 40 fg.
Point mutations do not change the mass of DNA.
• In chromosomal rearrangement, some daughter cells gain parts of
chromosomes and some lose parts of chromosomes.
• In nondisjunction, daughter cells gain a whole entire chromosome.

We saw that Calix gained part of the X chromosome from his father (chromosomal rearrangement).
O Calix's DNA was 40fg more than his father.
O Calix matched the X chromosome of his father AND his mother.
O Calix was orange and black and white. The white gene is also on the X chromosome.
O Calix's DNA was 15 fg heavier than his mother's DNA.
The pigment gene for cats (orange or black) is on the X chromosome. Calix had both colors.
