All organisms have genes.
Eye color is an example of a gene.
Genes affect traits.
Genes are passed down from parents to offspring.
In a group of cats, some individuals have straight fur and others have curly fur. In this group, the gene for the fur type trait has two alleles. The allele F is for straight fur, and the allele f is for curly fur.
Tabitha, a cat from this group, has straight fur. Tabitha has one allele for straight fur and one allele for curly fur.
Based on this information, what is Tabitha's genotype for the fur type gene?
Ff
straight hair
