Law of Dominance
Law of dominance is a principle in genetics that states some alleles are dominant while others are recessive. This means that when an individual has both dominant and recessive alleles for a particular trait, only the dominant allele will be expressed in the phenotype.
Gregor Mendel
Gregor Mendel, an Austrian monk, discovered the law of dominance through his experiments with pea plants in the 19th century. He observed that certain traits, such as flower color and seed shape, followed predictable patterns of inheritance.
Dominant allele is represented by a capital letter (e.g., B), while a recessive allele is represented by a lower case letter (e.g., b). When an individual has one dominant and one recessive allele for a particular gene, the dominant allele will mask the expression of the recessive allele.
Punnett Square
A Punnett square is a handy tool used to predict the probability of certain traits appearing in offspring based on the parents' genotypes. By using the principles of dominance and segregation, scientists can determine the likelihood of different genetic combinations.
Phenotype refers to the physical characteristics of an organism, such as eye color or hair texture, resulting from the expression of alleles. The genotype, on the other hand, represents the genetic code carried by an individual, including both dominant and recessive alleles.
In conclusion, the law of dominance plays a crucial role in understanding how genetic traits are inherited and expressed in living organisms. Through the diligent work of scientists like Gregor Mendel, we can unravel the mysteries of heredity and appreciate the complexity of genetic diversity.
