Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
- Using A to represent the alleles
- Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
- So for John to have an unattached earlobe, his father has to be either AA or Aa.
- Therefore John's genotype would be Aa

1 - V=150 cm3
2 - 180 divided by 150= 1.2 g/cm3
3 - The mass would stay the same on the moon as on Earth because mass is just how much matter is in an object. However, the weight would be different because the gravitational pull is weaker on the moon than it is on Earth.
4 - The density is greater than the density of water which is 1 g/cm3.
5 - No because one solid could be a heavier material than another solid.
9 - Mass: gram (g) or kilogram (kg). Volume: liter (L) or centimeter (cm). Density: g/cm3 or g/mL
