Answer/Explanation:
Given==> short tail allele (T) is dominant, and long tail allele (t) is recessive.
Genotype of homozygous short-tailed dog = TT, while genotype of heterozygous short-tailed dog = TT
Required==> Punnett Square showing a genetic cross between both parents: i.e. TT X Tt
*See attached image for the Punnett Square
From the Punnett Square, 50% of the offspring of the First generation would be homozygous short-tailed, while 50% would be heterozygous short-tailed.
All the offspring would be all short-tailed as well.
