Presentation on theme: "Introduction to Genetics Heredity….. Gregor Mendel Austrian Monk --Discovered a “pattern” while working in the garden PEAS have “traits” or characteristics."— Presentation transcript:
Realization from MENDEL *The offspring must “get genetic information” from the parents…. ½ from mom ½ from dad This genetic information is “DNA”. Sections of your DNA are called “GENES”, the instructions for specific traits…..(such as code for color of the pea flower)
GENES Now, there can be “variations” of a gene. --Red or white flower pea plants These “variations” are called ALLELES. To represent these variations (alleles), we will use LETTERS. DOMINANTRECESSIVE A trait that seems to “overtake” another trait A trait that seems to “hide” and then suddenly appear in a generation. Capital letters to represent the ALLELES Lower case letters to represent the ALLELES Red = RWhite = r
