Abstract:
The aim of this study is to present a short biography of some important physicians and describe the most prominent differences between trisomy 13, 18 and 21. The authors present the most prominent differences between trisomy 13, 18 and 21. The work of many important physicians, geneticists, has helped in the process of recognition of congenital anomalies. This group of famous persons includes Patau, Edwards and Down.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
