Question

Dragon color and wing size are controlled by two separate gene loci with 2 alleles each. A dragon that is red with large wings (RrWw) mates with another that is silver with small wings (rrww).


a. Write out the genotypes of the 4 gametes (of each parent) that will be used to determine the resultant offspring from the cross.
b. Do a Punnett Square to demonstrate all the possible resultant offsprings’ allele combinations (genotypes) from parents having genotypes RrWw and rrww.
c. What is the resultant genotypic ratio? phenotypic ratio?
i. (Be sure you indicate what each part of the ratio refers to, i.e. don’t just say 4:3:2. Say what the numbers refer to)
