Genetics N’ Stuff
Who Came Up with This? Gregor Mendel Proposed theory of heredity –Traits are passed from parents to offspring
He worked with pea plants short tall
Why did the tall override the short? Dominant= trait that is bossy Recessive= trait that gets masked
Section 10.1 Summary – pages TT T T tt t t Tall plant Short plant All tall plants tall plant passes on “T” allele = letter dominant over “t” allele
Why does each trait have 2 letters? A letter is passed from each parent Hello! Heredity
Homozygous- 2 same size letters HH or hh Heterozygous= different size letters Hh
If I have genotype Ww, and W=round snoot and w=pointy snoot, what will my phenotype be? Physical trait= round snoot!!
Phenotype= physical trait Genotype = letters or alleles
Let’s do an example with a punnett square!
If there are only brown dominant chickens and white recessive chickens, how could you get a red chicken? Incomplete dominance
Incomplete= 2 phenotypes mix to make a medium trait Codominance= when both phenotypes show up –Example= blood type
But what about height? There are way more than 2 or 3 sizes of person! Polygenic Traits
Polygenic Traits More than one allele controls it Examples: height,
Traits can also be linked by 9sex Only boys get color blindness Hemophilia
