Dog Kennel Brochure
• You will be creating a brochure to advertise your Dog Kennel.
• You “design” puppies using your knowledge of genetics and patterns of inheritance.
• You must choose 5 traits that your puppies have:– 3 must be inherited by dominant/recessive alleles– 1 is inherited by incomplete dominance– 1 is inherited by codominance
Instructions
1. Create a title page:– Title (name of kennel), your name, and a picture
2. On section 2, list and define the following terms:– Genes– Genotype– Phenotype– Heterozygous– Homozygous– Dominant– Recessive– Chromosome
Instructions
3.In section 3, describe 5 traits that you want to look at in the dogs that you are breeding for.– 3 traits must show dominant/recessive
inheritance• What trait is dominant?• What trait is recessive?
– One trait must show incomplete dominance.– One trait must show codominance.
Instructions
• In sections 4 and 5, create Punnett squares for each of the 5 traits you picked for your dog:– Create the Punnett squares.– Label the Punnett squares with the characteristic
(ex: fur color).– Identify the dominant and recessive alleles and
their corresponding traits.– Include the probability on ALL Punnett squares of
each genotype and phenotype.
Incomplete Dominance & Codominance
• Incomplete dominance - blending or mixing of the parents’ traits– Ex: red + white = pink
• Codominance – both parents’ traits appear together– Ex: red + white = red & white
