  1. Bellwork: Wed. Jan. 18 , 2017 Short hair is dominant: SS… Ss long hair is recessive: ss 1. Show a cross between two heterozygous guinea pigs. What % of the offspring will have short hair?  ________ What %of the offspring will have long hair?  _______ 2. Two short haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents?  ________   x  ___________

  2. How to Set up a Dihybrid Cross And Punnett square

  3. Traits: Curly Hair (A) Straight Hair (a) Brown Hair (B) Blonde Hair (b)

  4. How to Set up a Dihybrid Cross Curly Hair (A) Straight Hair (a) Brown Hair (B) Blonde Hair (b) Do this: AaBb X AAbb Genotypic Ratio: Phenotypic Ratio

  5. Hair Color, Texture Cross Cross a female with homozygouscurly, heterozygous brown hair to a male with, straight blonde hair: 1st, write the cross: Curly Hair (C) Straight Hair (c) Brown Hair (B) Blonde Hair (b) ________ x ________ Genotypic Ratio: Phenotypic ratio:

  6. curly

  7. How to make the “key” for your Llama crosses: KEY: F = Floppy ears L = Normal legs f = pointy ears l = bow legs

  8. Bellwork: Tues. Jan. 12, 2016 White coat color (WW) is co-dominant to red coat color in cattle (RR). What should the genotypes and phenotypes be for parental cattle if a farmer wants only cattle with roan coats. Cross:____________________ Genotype(s): Phenotype(s) 2. A florist has flowers that exhibit incomplete dominance. Red petals are incompletely dominant to white petals. What would the genotype(s) and phenotype(s) be for offspring of a red flower and a white flower? Cross:____________________ Genotype(s): Phenotype(s):
