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…
