Critical Thinking 6 Test cross is typically used in order to determine the genotype of an organism, which appears dominant. We can determine the unknown organism is whether homozygous dominant (AA) or heterozygous dominant (Aa) through crossing unknown with recessive (aa). If an organism that is homozygous dominant is crossed with recessive (AA aa), the result will produce 100% of Aa. If an organism that is heterozygous dominant is crossed with recessive (Aa aa), the result will produce 50% of Aa and aa each. Therefore, it is safe to say that key factor of determining

Unformatted text preview: unknown's genotype is through probability, which is based on observation. Thus, the result of test cross needs to produce measurable population of offsprings to some extent. If horses produce only one offspring, it is very hard to determine the genotype in terms of probability. In order to have accuracy and a successful test cross, the species of animal used must have at least 10 to 20 offsprings to determine from....
