An organism evolves to look like a an organism with an antipredator defense. The trend continues as more and more organisms in the species exhibit this harmless mimic. (Batesian mimicry) An organism with a bad taste evolves to look like an organism that stings. (Mullerian mimicry) What can be said about this?
a. Mullerian mimicry is limited and diluted. Batesian mimicry is unlimited.
b. Batesian mimicry is limited and diluted. Mullerian mimicry is unlimited.
c. Both are limited and diluted.
d. Both are unlimited and strengthen the organism.
I have answers, but I’d like a second opinion.

My teacher is not providing me with much guidance–this school has no curriculum (!!). I am about to teach a genetics unit and I was just wondering how you, if you teach high school bio, would go about the order of the following topics:
DNA
DNA replication
Transcription/Translation
Mitosis/Meiosis
Inheritance and Heredity
Human genetics
Biotechnology
Thanks!

I had to cross and follow the inheritance pattern of Drosophila flies with white eyes. This is a sex-linked recessive trait and is supposed to show up as a 1:1:1:1 ratio. How do I calculate an exact ratio from the data I generated?
F, whi: 103/424
F, red: 118/424
M, whi: 107/424
M, red: 96/424
I understand that it basically supports the 1-1-1-1 ratio, especially through the use of a Chi-square test, but since these values aren’t exactly the expected 106-106-106-106 that they’re “supposed” to be, what is the exact ratio for my data? Is it still technically 1-1-1-1? How do I go about calculating it?
Thanks!

In rabbits the allele for short hair (S) is dominant, the allele for long hair (s) is recessive. The allele for gree eyes (G) is dominant and the allele for blue eyes (g) is recessive. A cross between two rabbits produces a litter of six short haired rabbits with green eyes and two short haired rabbits with blue eyes. What are the most likely genotypes of the parent rabbits in this cross?

3.A purple haired woman marries a blue haired man. They have 10 blue haired daughters, 10 purple haired daughters, 9 red haired son, and 8 blue haired sons.
A purple haired daughter marries a red haired man. Half of their sons have red hair and the other half has blue hair. Half of their daughters have red hair and the other half has purple hair. One of their red haired daughters married a blue haired . All of the daughter have purple hair, 12 of the sons have red have and one son has purple hair. Explain the genetics of this family. What kind of trait is hair color? Be specific (i.e. complete dominant, co-dominant, incomplete dominant, non-X-linked, X-linked—mention any and all that apply). Explain the different genotypes associated with each phenotype. Does anyone have anything abnormal about their genotype.
