Presentation on theme: "Ex. Red and white flower produce pink offspring"— Presentation transcript:

1 Ex. Red and white flower produce pink offspring
Other Patterns of Inheritance Incomplete dominance- no recessive or dominant alleles. There is an incomplete dominance of one allele over another.  Ex. Red and white flower produce pink offspring -New format for Punnett squares

2 Codominance- both phenotypes show of the alleles in different locations
 Ex. Red and white alleles present for flower color= flowers with 
 red and white stripes

4 A red cow (RR) is crossed with a roan cow (RW)
A red cow (RR) is crossed with a roan cow (RW). 
What are the possible genotypes and phenotypes of 
the offspring?

5 A pink flower (RW) and a pink flower (RW) are crossed
A pink flower (RW) and a pink flower (RW) are crossed. What are the 
genotypes for the flowers if red flower color is represented by R and 
white flowers are represented by W? What are the potential 
genotypes and phenotypes of their offspring?

6

7 Multiple Alleles- one gene can have multiple alleles 
(not per individual but as options in a population)

8

9

10 Polygenic Traits More than one gene codes for a trait  Ex. Skin color

11 Genes and the Environment
-Phenotype only partly due to genotype -Also due to environmental effects
