PPT-Dominant and Recessive Traits in Humans

What are the Dominant and Recessive Traits in Humans There are over 200 traits that are transmitted from generation to generation in humans These interesting aspects of human genetics are known as hereditary traits. Heredity: the passing of genetic traits from parent to offspring. A feature that has different forms in a population . Different forms of a characteristic governed by genes. Characteristics:. Hair Color. Clarification:. Genes. are not recessive or dominant.. Alleles. of genes are not recessive or dominant.. The . proteins made by alleles of genes . are not recessive or dominant.. You cannot tell if a trait is recessive or dominant based on the genes that affect it or the alleles in a population.. What did Mendel Observe?. How do alleles affect inheritance?. Heredity. The passing of physical characteristics, or traits from parents to offspring.. VOCABULARY. Genetics: The study of Heredity (passing of traits from parent to offspring). What are the Dominant and Recessive Traits in Humans?. There are over 200 traits that are transmitted from generation to generation in humans. These interesting aspects of human genetics are known as hereditary traits. Page 281. Concept Check . 14.4. Answer 1 and 2. 1/28 . Daily . Catalyst . Pg. 75 Pedigrees. Quiz #18 on Thursday.

These are some of the common dominant and recessive traits in humans that can be easily observed in people around you. . You . have two genes for them. One inherited from your father and one from your mother. The way that a physical trait is expressed, and hence the way you look is a result of either a combination of dominant genes, a dominant and a recessive gene or two recessive genes..

The allele for . short fur (F) is dominant. , while the allele for . long fur (f) is recessive. .. Female. Male. S. hort . fur (F) is dominant; long fur (f) is recessive.. Chapter 4 Sections 1and 2. Parents and offspring are similar.. We all have our own unique combination of characteristics. These are called traits. There are two types of traits:. Inherited traits resemble those your birth parents have, like hair color, eye color, blood type.. X-LINKED DOMINANT INHERITANCE. X-LINKED INHERITANCE. dr. . Retno. . Sutomo. , Ph.D., . Sp.A. ..

The study of heredity or how traits are passed from parents to offspring. Genetic Material. Chromosome. Rod shaped structure in the nucleus of a cell consisting of genes. Occur in pairs except in the reproductive cells . 1. Gregor. . mendel. Gregor. Mendel is the father of genetics. He came up with the Law of Segregation and the Law of Independent Assortment. In 1857 he began breeding garden peas to study inheritance. He was also a monk. . June, 2002. Heredity. Passing of traits from parent to offspring. Genes. Gene – segment of a chromosome that contains the heredity traits of an organism. Genes. Basic units of biological inheritance.
