1. The length of a dog's tail is an inherited trait. The allele for short tails is dominant (T) over the allele for long tails (t). A dog breeder mates two short-tailed dogs (parents). One parent is
homozygous and the other is heterozygous for this trait (10 points).
a. Complete the Punnett square for the genetic cross described above:

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.

covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
