1) In cats, the allele for white fur(W) is completely dominant and will result in cats with all white fur in both the homozygous dominant and heterozygous cases. Suppose you look at 50 cats and notice that none of them are completely white. What's the allele frequency for the white fur allele in this population? 2) In carnations, the allele that makes red pigment (R) in flowers is incompletely dominant. Flowers that are red are homozygous dominant and those are pink are heterozygous. White flowers (r) are the result of the recessive allele. Suppose you look at a field of 100 carnations and notice 42 of the plants produce red flowers, 42 have pink flowers, and 16 produce white flowers. What's the allele frequency for both the red (R) and white (r) alleles?
