Cleft chin
- Cleft chin is a dominant trait, which means that having the dominant allele either from one parent (Bb) or both parents (BB) will always result in the phenotype associated with the dominant allele.

Dec 20, 2023 · Dominant genes are those that are expressed or “seen” in an organism’s physical traits, even if only one copy of the gene is present. They are the genes that override or mask the effects of recessive genes if both are present.
A dominant gene refers to a specific gene variant that is more likely to be expressed in an organism’s phenotype over another alternative gene variant, known as a recessive gene. Dominant genes are able to exert their influence even when present in only one copy within a pair of corresponding chromosomes.
In this example, we will call the gene for cleft chin “B,” and the gene for smooth chin “b.” Cleft chin is a dominant trait, which means that having the dominant allele either from one parent (Bb) or both parents (BB) will always result in the phenotype associated with the dominant allele.

Psychologists study genetics in order to better understand the biological factors that contribute to certain behaviors, thoughts, and feelings. Our genes provide a “blue-print” for making the proteins that are the building blocks of our bodies, including our nervous system.
