1.)in grackles (a type of bird), long tails (L) are dominant to short tails (l). If two grackles that are heterozygous for tail length mated, the offspring might have which genotype?
2.) Saguaro cacti are very tall cylindrical plants that usually have two L-shaped arms, one one each side. In the Saguaro arm length is controlled by a single gene with arms of the same length (A) being dominant to arms of different lengths (a). If two cacti that are heterozygous for arm length are mated, the offspring would be expected to show which phenotypic ratio?
3.) In wolves the normal coat color (N) is dominate to black (n) and brown eyes (B) are dominate to blue (b). If a homozygous normal color coat wolf with brown eyes is crossed with a homozygous black coat wolf with blue eyes what is the phenotype of the F1 progeny?
