As I promised in the discussions...

Lets say...

f - is a reccesive gene for attached earlobes

F - is a dominant gene for detached earlobes

Table 1

Table 2
 * Father's genotype || Mother's genotype ||
 * FF || ff ||


 * ||  || Sperms || Sperms ||
 * ||  || F || F ||
 * Ovary || f || Ff || Ff ||
 * Ovary || f || Ff || Ff ||

Offspring's genotype - Ff

There will be a 100% chance of getting detached earlobes.

Notes

Dominant trait is a trait that is shown

Reccesive trait is a trait that is NOT shown

Genotype is genetic makeup (NOT the makeup your mother uses!)
