Application of Mendelian Laws to Humans
Here are some real-life examples of Mendelian genetics in human as mentioned below.
| Trait | Dominant Allele | Recessive Allele | Phenotypic Ratio in Offspring (F1 Generation) | Phenotypic Ratio in Offspring (F2 Generation) |
|---|---|---|---|---|
| Hair Color | Brown (B) | Blond (b) | All offspring have brown hair (Bb) | 3:1 ratio of brown hair (BB or Bb) to blond hair (bb) |
| Tongue Rolling | Rolling (R) | Non-rolling (r) | All offspring can roll their tongue (Rr) | 3:1 ratio of tongue rollers (RR or Rr) to non-rollers (rr) |
| Hitchhiker’s Thumb | Hitchhiker’s (H) | Straight (h) | All offspring have hitchhiker’s thumb (Hh) | 3:1 ratio of hitchhiker’s thumb (HH or Hh) to straight thumb (hh) |
| Attached Earlobes | Attached (E) | Free (e) | All offspring have attached earlobes (Ee) | 3:1 ratio of attached earlobes (EE or Ee) to free earlobes (ee) |
| Blood Type | Type A (IA) | Type O (i) | All offspring have blood type A (IAi) | 3:1 ratio of blood type A or B (IAIA, IAi, IBi) to type O (ii) |
| Freckles | Freckled (F) | Non-freckled (f) | All offspring have freckles (Ff) | 3:1 ratio of freckled (FF or Ff) to non-freckled (ff) |
| Bent Little Finger | Bent (B) | Straight (b) | All offspring have bent little finger (Bb) | 3:1 ratio of bent little finger (BB or Bb) to straight (bb) |
| Eye Color | Brown (E) | Blue (e) | All offspring have brown eyes (Ee) | 3:1 ratio of brown eyes (EE or Ee) to blue eyes (ee) |
| Dimples | Dimpled (D) | Non-dimpled (d) | All offspring have dimples (Dd) | 3:1 ratio of dimpled (DD or Dd) to non-dimpled (dd) |

Applications of Mendelian Genetics
Real-life Applications of Mendelian Genetics: Mendelian Genetics is a specific type of inheritance in the field of biology. It describes how genetic traits are passed to offspring from their parents. Mendelian Genetics focuses on the laws of segregation and specifically on the independent assortment.
In this article, we are going to discuss the Real-life Applications of Mendelian Genetics in detail.
