Genetic crosses involving single genes (monohybrid inheritance) can be shown and examined using Punnett squares. The tall allele is dominant and is shown as T. The small allele is recessive and is ...

When you see a dominant trait, the underlying genetic make-up can still be ambiguous. See how researchers use test crosses to find out the genotype behind the phenotype. The test cross is another ...

Early use of the test cross was as an experimental mating test used to determine what alleles are present in the genotype. An organism's genetic makeup is called its genotype, and it reflects all ...

In this genetic cross, the female alleles are Dd and the male alleles are dd. This cross is known as a backcross. Half of the possible offspring have the allele combination Dd, and the other half ...
