Name the 5 principles of the Hardy-Weinberg Equilibrium.

Hardy-Weinberg equilibrium states that in order to remain in equilibrium, the population must:
1. be fairly large.
2. have no immigration or emigration, because this may introduce new genes into the gene pool.
3. Must carry out random mating, because selective mating will favor a certain trait.
4. Must have no natural selection
5. No genetic mutations?? Hope I got that right...

Nondisjunction occurs when pairs of homologous chromosomes or sister chromatids fail to split during meiosis, which causes the gametes produced to have more or less than the normal number of chromosomes (23 for gametes). Extra or missing chromosomes in offspring (chromosomal aneuploidy) causes disorders such as Down syndrome (trisomy 21) and Klinefelter syndrome (XXY syndrome), to name a few.

2. DNA is in a double helix structure, or two strands of DNA intertwined around each other. A strand of DNA is made of subunits known as nucleotides, which are made up of a nitrogenous base (adenine which pairs with thymine; guanine with cytosine), a pentose (five-carbon) sugar, and a phosphate group which is attached to the 3' and 5' carbons to the sugars above and below it. The nitrogenous bases are held together by hydrogen bonds and the two strands run antiparallel to each other (I hope this was enough).

3. I would need the genotypes of the parents to perform a dihybrid cross.

I think he means the general ratio you need to remember for a dihybrid cross (ex. number:number:number:number)

It's been a while, but I think you're meant to assume both parents are heterogenous in both traits here.

(P.S. is the answer 9:3:3:1?)
