18. In rabbits, the allele for black coat (B) is dominant over the allelefor white coat (b). What would the offspring be if you crossed two heterozygous parents? 3 black : 1 white -------------------- 1 Hom Dominant 2 Heterozygous 1 Hom Recessive

19. What would the offspring be if you crossed a heterozygousrabbit with a homozygous dominant rabbit? 100% Black -------------------- 50% Homozygous Dominant 50% Heterozygous B b B B

20. In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. How would you describe the genotype of offspring Eeww? homozygous dominant for earlobes & homozygous dominant for widows peak homozygous recessive for earlobes & homozygous recessive for widows peak heterozygous for earlobes & homozygous recessive for widows peak C
