In Snarlydragons, the number of teeth is polygenic trait.  The recessive condition (aabbcc) results in a toothless Snarlydagon, and the dominant condition (AABBCC) results in a Snarlydragon with 6 teeth.   1. What is the phenotypic probability (how many teeth) % and ratio of having a baby snarlydragon with 4 teeth between parents with genotypes AABBCc x AAbbcc?

Please use the letter A (tall) or a (short) for height and the letter B (pointed head) or b (non-pointed head) for head shape.  You discover two new genes on different chromosomes for head shape and height in aliens. A homozygous recessive female that is short and is heterozygous for head shape (pointed) mates with a homozygous dominant (tall) male for height that is also homozygous dominant for head shape (pointed). Create a punnett square and answer the questions below.    1. What is the genotype of the male parent in the problem ? 2. What is the phenotype with regards to head shape of the female parent in the problem ? 3. What percent of offspring are heterozygous for height ? 4. What percent of offspring are homozygous dominant for head shape ? 5. What percent of offspring are short with a pointed head ?

MoveOn.org was one of the first groups to successfully organize people around issues like partisan bickering and the power of corporate lobbies in Washington. This was, in large part, because it used innovative technology to locate, recruit, and organize supporters. This is exactly what __________ theory would predict.

Many parents today are worried about the bottles out of which their babies drink, because many contain plastics made with bisphenol A (BPA). This is a compound that helps to make hard, clear, shatterproof plastics, but it might also be a neurotoxin to which children may be especially vulnerable. Science has yet to fully explore this issue, but what era of the environmental movement does this concern most closely follow?
