Answer:
To determine the possible outcomes of crossing a smooth-haired Bashkir horse with a curly-haired Bashkir horse, you need to know the inheritance pattern of the curly hair trait in this breed. If a single gene determines the trait with two alleles (curly and straight), the Punnett square can be used to predict the possible genotypes and phenotypes of the offspring.
Assuming that the curly hair trait is dominant over the smooth hair trait and that both parent horses are heterozygous for this trait (Cc for the curly-haired horse and cc for the smooth-haired horse), the Punnett square would look like this:
See attachment:
So, there is a 50% chance that the offspring will have curly hair (either CC or Cc genotype) and a 50% chance that the offspring will have smooth hair (cc genotype).
To confirm the actual genotypes and phenotypes of the offspring, a test cross can be performed by breeding the offspring with a homozygous recessive individual (cc). This would reveal the genotype of the offspring by the ratio of curly to smooth-haired offspring. If all offspring have curly hair, then they must be homozygous dominant (CC); if they have both curly and smooth hair, then they must be heterozygous (Cc); and if all offspring have smooth hair, then they must be homozygous recessive (cc).
