Monohybrid Cross Punnett Square Explained | Genetics Guide #145905 (License: Personal Use)

This Punnett square displays the four possible allele combinations resulting from a cross between two heterozygous parents (Tt × Tt), yielding genotypic ratios of 1 TT : 2 Tt : 1 tt. The uppercase 'T' denotes a dominant allele, while lowercase 't' represents a recessive allele-commonly used in introductory genetics education. It serves as a foundational tool for predicting inheritance patterns in Mendelian traits.

Used in biology textbooks, online genetics tutorials, and classroom instruction to teach basic Mendelian inheritance; targets students and educators seeking to understand genotype probability and allele segregation.
