Predict Genetic Outcomes
Used by biologists and students worldwide, the Punnett Square allows you to visualize potential offspring genotypes from a breeding experiment. This tool handles a simple "Monohybrid Cross" (tracking one trait).
Key Terms
- Homozygous: Two of the same alleles (BB or bb).
- Heterozygous: Two different alleles (Bb).
- Phenotype: The observable characteristic (e.g., Brown Eyes) resulting from the genotype.
Frequently Asked Questions
What is a Punnett Square?
A Punnett Square is a graphical representation used to determine the probability of an offspring having a particular genotype based on the parents' genetic makeup.
What do capital and lowercase letters mean?
A capital letter (e.g., B) represents a Dominant allele, while a lowercase letter (e.g., b) represents a Recessive allele.
Can this predict eye color?
It can predict simple Mendelian traits. However, complex traits like human eye color are polygenic (controlled by multiple genes) and are better served by our specialized Baby Eye Color Calculator.
