• They are the physical appearance of a organism 
• They show (in this case) what the dog or wolf will be
• Ex: short hair, long hair, grey, white, male, and female

what are genotypes

• Genotypes are the letters for a phenotype
• Genotypes are both big and small letters
• Ex: LL for homozygous long hair, Ss for heterozygous short hair, or ss for 
• homozygous short hair

Wolves and dogs have the same amount of genetic material

• Dogs and wolves have 78 chromosomes
• Dogs and wolves are 98% the same genetic material

dog genotype and phenotype

• Dogs can have long or short hair
• Dogs can be given a trait to run fast
• There are over 500 genotypes and phenotypes dogs can have 
• The genotype for a long hair homozygous dog is LL

Wolves genotype and phenotype

• A phenotype is long hair
• Another phenotype is short hair
• There are over 300 phenotypes in a wolf 
• The short hair hybrid genotype looks like this Ss

HEterozygous dog and wolf Genotype

• Dogs can have many different genotypes 
• Hybrid genotypes are made of one big letter and one small letter
• If a wolf was a heterozygous short haired wolf it would have one big S
• and one small s

Background on Wolves and dogs

• Wolves have the same number of chromosemes as dogs    
• Dogs are 98% genetically similar to wolves 
• Wolves have been on the Earth for 12,000 years 
• Dogs have many breeds

Dog Breeds

• Labrador Retriever 
• Golden Retriever
• German Shepherd
• Each one of these dogs have different phenotypes
