OFFSPRING MODEL

QUESTION

BACKGROUND RESEARCH

• Genotype: is the name for the alleles an organism has
• Phenotype: describes the actual characteristics that can be observed
• Dominant: allele is one that is expressed in the phenotype
• Recessive: is an allele that is only expressed when two copies of it are present

Hypothesis
If we choose alleles from six bags then we will be able to determine what the the offspring will look like because the genotype is located on the allele.
