Punnett Square Genetics

Recessive Alleles Takes two alleles to be expressed.

Multiple Alleles. allele = (n) a form of a gene which codes for one possible outcome of a phenotype For example, in Mendel's pea investigations, he found.

Exceptions to Mendelian Inheritance. Mendelian Inheritance means… one gene = one trait 2 different alleles (versions) for a gene one dominant and one.

Catalyst In guinea pigs, black coat is dominant to brown coat. What would be the possible genotypes for a black guinea pig? What is the genotype for a.

Codominance "co-" is "together".  Refers to a relationship between two alleles of a gene. Both traits appear in an organism. They do not overpower each.

Blood Types. Genetics of Blood Your blood type is established before you are born, by specific genes inherited from your parents.

There is no dominant allele, There is no recessive allele. Both alleles “blend” to result in a third phenotype.

Blood Type AA AO BB BO AB OO A B O Trait controlled by multiple alleles Alleles are A, B, and O Genotype AA AO BB BO AB OO Phenotype A B O 1. Which alleles are dominant? A, B over O O 2. Which alleles are recessive? 3. Which alleles are codominant? A and B

A B AB O A B AB O Blood type Can receive from: Blood type Can donate to:

Blood Type Problems Bob has A type blood and Emily has B blood. Their child has O blood. Identify the genotypes of all 3 people. Calculate the probability that Bob and Emily will have a AB child. Raul has A blood. Raul and his wife Isabel have a child with AB blood. Identify the possible genotypes of all three

Blood Type Problems Leo has B blood type. His wife Sherri has AB blood. Half of their children have AB blood, and half of their children have B blood. What is Leo’s genotype? 4. If Leo and Sherri’s child, Roxy, gets in an accident and loses a lot of blood, which parent can donate blood to Roxy, who has AB blood.
