how you express your genotype; ex. blonde hair, brown eyes, etc…
Genotype refers to the specific genetic instructions or sequence of DNA that you inherit from your parents
Genotype refers to the specific genetic instructions or sequence of DNA that you inherit from your parents. It determines the traits and characteristics that you may possess. While your physical appearance, such as having blonde hair or brown eyes, can be influenced by your genotype, it is actually the phenotype that describes the observable traits.
To express your genotype, you can use a combination of specific letters and symbols that represent the alleles (alternate forms of a gene). Each gene is typically represented by two alleles – one inherited from each parent. The combination of these alleles determines the expression of a particular trait.
For example, let’s consider the trait for hair color. The gene responsible for hair color can have different alleles such as “B” for brown hair and “b” for blonde hair. If you have inherited the “Bb” combination, it means you have one allele for brown hair and one for blonde hair. In this case, the dominant allele “B” will determine your hair color, and you would have brown hair.
Similarly, for eye color, you might have the gene with alleles “E” for brown eyes and “e” for blue eyes. If you inherit the combination “Ee,” you would have brown eyes as the dominant allele “E” determines the expression of this trait. On the other hand, if you inherit two copies of the recessive allele “ee,” you would have blue eyes.
It is important to remember that many traits are more complex and involve the interaction of multiple genes and environmental factors. In some cases, a single gene may not solely determine a trait. Nonetheless, expressing genotypes often involves using letters or symbols to represent the alleles carried by an individual and understanding how they contribute to the expression of various traits.
