Understanding the Inheritance of Dwarfism in Horses

In horses, the gene for dwarfism is dominant over the gene for normal height. Let's explore the potential offspring when different types of horses are bred.

1. Offspring of a Heterozygous Dwarf Horse and a Homozygous Normal Horse:

When a homozygous dwarf horse (carrying two copies of the dwarfism gene) is crossed with a homozygous normal horse (carrying two copies of the normal height gene), the offspring will all be heterozygous for the dwarfism gene. This means that all the offspring will inherit one copy of the dwarfism gene and one copy of the normal height gene. As a result, all the offspring will exhibit the dwarfism trait, as the gene for dwarfism is dominant.

2. Offspring of Two Heterozygous Dwarf Horses:

When two heterozygous dwarf horses (each carrying one copy of the dwarfism gene and one copy of the normal height gene) are crossed, the Punnett square can be used to determine the potential offspring. In this case, there is a 25% chance of producing a homozygous dwarf horse, a 50% chance of producing a heterozygous dwarf horse, and a 25% chance of producing a homozygous normal horse.

It's important to note that these predictions are based on Mendelian genetics and assume no other complicating factors.
