A Punnett square that shows the possible genotypes of the offspring of two heterozygous raccoons:
L L
L LL Ll
L Ll ll
Since long fur is dominant to short fur in raccoons, a cross between two heterozygous raccoons (Ll x Ll) will produce offspring with the following genotypes and phenotypes:
Genotype: 1/4 LL (homozygous dominant), 1/2 Ll (heterozygous), and 1/4 ll (homozygous recessive)
Phenotype: 3/4 long fur and 1/4 short fur
So, This means that there is a 75% chance that any offspring of these two raccoons will have long fur, and a 25% chance that they will have short fur.
