Genetics
Genetics By: Alexis Bryant Page 1: Genetics- Breaking down the definitions The definition of Genetics is the study of heredity. Heredity is when a parent or their ancestors pass traits to their offspring. Many things can be hereditary, like physical characteristics and illnesses. Heredity traits passed down from your parents to you that influence your DNA. DNA stands for deoxyribonucleic acid. DNA strands are basically the blueprint that living organisms use to develop and function. So really, Your DNA is the brain of heredity.

Fun Fact!!!! DNA has 2 backbones going down the sides. It looks like a ladder being twisted up.

DNA is to brain as cold is to ice Page 2: Changing dna Fun Fact- Genetic engineering HAS to be done in a lab. Did you know that it is possible to change your DNA? The process is called “Genetic Engineering.” Genetic engineering involves altering the genetic structure of embryonic cells or vectors to provide them with desired traits or to eliminate undesirable traits. For thousands of years, humans have engaged in primitive forms of genetic engineering. They have chosen plants or animals with survival strength and desirable characteristics for further breeding, and have combined different strains of a species in attempts to retain and emphasize desirable characteristics of both.

Genetic engineering is to changing as dessert is to dry.

Page 3: selective Breeding FUN FACT--- People who used selective breeding were shuned by surrounding people and they had problems selling their products. Selective Breeding is the process of selecting & breeding together parent organisms to pass on particular traits to offspring. Selective breeding can be successful as long as the desirable traits are controlled by genes. Before selective breeding was widely known, people who performed selective breeding were accused of trying to change DNA to destroy nature’s natural balance, but that was not the case. The only thing they were doing was causing certain alleles to become more common in certain animals. Not completely change their DNA.

Selective breeding is to DNA as computer is to screen

Page 4: Gregor Mendel -Fun Fact--- Mendel was made abbot of the St. Thomas Monastery in 1868... His birthplace of Hyncice is also known by its former German name, Heinzendorf. A monk with a scientific streak, Mendel made botanical discoveries which became the basis of modern genetics. His careful cross-breeding of thousands of pea plants led Mendel to key insights, now called Mendel's Laws of Heredity, about how inherited traits are passed on from generation to generation. As a young man Mendel entered the St. Thomas Monastery in Brünn, Austria. He devoted much of his time to teaching. Between 1856 and 1863 he catalogued successive generations of pea plants with statistical precision, looking for clues to how traits like color and shape were reproduced. Among his findings were the law of segregation and the law of independent assortment. Mendel published Experiments in Plant Hybridization in 1865, but they weren’t widely embraced until the 1900s.

Gregor Mendel is to genetics as mother is to daughter
