5. Purple snapdragons are crossed with white snapdragons. Purple color shows compete dominance to white color. Find the genotypic and phenotypic ratios of the F2 offspring from a cross of homozy- gous parents 6. In watermelons, the allele for green rinds is completely dominant to the allele for striped rinds. You are given a melon with a green rind and asked to establish a pure-breeding line. How would you proceed? 7. A boy decided to raise rabbits. He found a variety he like, a mottled black and white. He bought a male and a female, and bred them. The litter consisted of 7 mottled rabbits and 1 white rabbit. a) On the basis of the data, what hypothesis would you make regarding the inheritance of the char- acteristic the boy desired? b) Were the rabbits homozygous or heterozygous?Explanation / Answer
