SpongeBob Genetics and Traits

The video tutorial covers SpongeBob genetics, focusing on phenotypes and genotypes. It explains dominant and recessive traits, and how to use Punnett squares to predict genetic outcomes. The tutorial includes practical examples and family scenarios to illustrate genetic inheritance patterns.

What is the dominant gene for SpongeBob's body color?

• Red

• Green

• Yellow

• Blue

Which of the following represents a recessive trait for SpongeBob's eye shape?

If a trait is heterozygous, what does it mean?

• Both alleles are the same

• One allele is dominant, one is recessive

• The trait is not expressed

• Both alleles are recessive
