Heredity B/Designer Genes C

Post by Nano1llus10n » September 3rd, 2018, 8:23 pm

Welcome to a new season, let's start off with something relatively basic:

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...

Thanks, will keep that in mind.

1. What is nondisjunction, and what are some possible consequences of this?
2. Describe the composition and structure of DNA.
3. What is the resulting phenotype ratio of a dihybrid cross?

1. 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)
island trash trees hs
anat: reg 4th
herp: reg 6th
genes: reg 5th
protein: reg 2nd
disease: reg 15th
fossils: reg 4th
2016: a&p 1st, fossils 3rd
2017: a&p 3rd, herp 14th

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?)

It's "she." But yes, that's what I was looking for.
Your other answers look good!

Yep, that's correct!

1. Why is mitochondrial DNA maternally linked?
2. Label the parts of this operon: Image
(don't label the top part that just says "operon"
3. Describe the function of each part.
