Tactile Punnett Squares Sheets (1-08890-00) (1-08891-00)

A Punnett square is a diagram that is used to predict the outcome of a particular genetic cross or breeding experiment. The Tactile Punnett Squares Sheets are designed for use by students who are blind or have low vision disabilities and com in 4-box and 16-box varieties. Punnett Squares are used by biologists to determine the probability of offspring genotypes. The Punnett Square is a visual representation of Mendelian inheritance.

The 4-Box Tactile Punnett Squares Sheets allows your students to predict offspring genotypes and probabilities for one character from the known genetic makeup of two parents; for example, a monohybrid cross or a test cross. Each of the four boxes of the Punnett Square easily accommodates four braille cells across. Two 4-Box Punnett Squares are printed and embossed on heavy 8.5 by 11 inch paper, 25 sheets per re-sealable envelope.

The 16-Box Tactile Punnett Squares Sheets allows your students to predict offspring genotypes and probabilities for two characters from the known genetic makeup of two parents; for example, a dihybrid cross. Each of the 16 boxes of the Punnett Square accommodates eight braille cells across. One 16-Box Punnett Square is printed and embossed on heavy 11.5 by 11 inch paper, 25 sheets per re-sealable envelope.
