The sex of an individual is determined by

the inheritance of XX or XY chromosomes

When a mutation occurs, what could happen to the protein coded for by that gene?

It might not be the right shape to carry out its function

Which is true for both Meiosis and Mitosis:

Meiosis: 4 daughter cells, mitosis: 2 daughter cells

The genetic code provides the instructions for...

...making proteins, ...making a sequence of amino acids

The fusion of gametes in human cells (fertilisation)...

...causes the chromosome number to be restored to normal

What is the cause of polydactyly?

A dominant allele for the number of digits

Define the term homozygous

Genome contains two of the same alleles for that gene

The definition of a genome is:

All of the genetic material of that organism
