Genes play a role in our likelihood of developing depression, and one of the most extensive studies of its kind has now been ...

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 ...

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 ...

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 ...

If you want to know what F1 Hybrid Seeds are, explore our detailed guide and learn about their benefits the best way to ...

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 ...
