- A. This is a Gruffalo (Donaldson, J, 1999, Puffin Books). It is a terrifying looking animal who is the biggest, baddest creature in the whole dark wood. Other animals are very afraid of it, as it is a top predator. Gruffalos release lots of olfactory chemicals marking them as predators that are smelled by other animals, and these chemicals vary from gruffalo to gruffalo depending on their genotypes (specific genes and related alleles are not known, just know that gruffalos vary for genetic reasons). There is variation in the olfactory chemicals released when gruffalos are in different types of forests (i.e. not just deep darks woods), where some gruffalos increase their olfactory chemicals, and some decrease. Draw the associated reaction norms for 4 genotypes of gruffalo in two different forest environments, and name the mechanism acting here Additionally, all gruffalos are tricked by little brown mice, where gruffalos think they are prey animals when in the presence of little brown…Part B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…Assuming both hemophilia and red-green colorblindness are rare traits, who is doubly heterozygous for sure?

Saguaro cacti are very tall cylindrical plants that usually have two L-shaped arms, one on each side. Suppose you live in southern Arizona where the Saguaro cactus is common, and you happen to have one growing in your yard. Your Saguaro has two arms, but one is longer than the other. Now, assume that arm length in these cacti i controlled by a single gene with arms of the same length (A) being dominant to arms of different lengths (a). What is the genotype of your cactus?
