What is half set of DNA

Chromosomes are found in a cell's ______.
What is the nucleus.

Albinism is a recessive genetic disease that makes your skin and hair white, and your eyes red. This is because the gene for making melanin (the protein responsible for colour) is defective. Normal = N (dominant) Albino = n (recessive). If Albino is the affected trait, what is the symbol for a female who displays the albino trait?

What is a coloured circle?

Two parents are heterozygous for a certain trait. What are the odds of them creating a homozygous recessive offspring?
What is there will be a 25% chance of a homozygous recessive offspring.
400
Having two different copies of the same gene...
What is heterozygous
400
A gene that you have that does not show in your phenotype
What is recessive gene.

Describe at least one way that mitosis and meiosis are similar and at least one way they are different.
What is they are similar because they both start by copying a cell's DNA. They are different because mitosis creates diploid cells and meiosis creates haploid cells.
