“Skinny Pig Genetics!” Hairlessness in guinea pigs is a recessive trait. Students practice Punnett squares with this simple worksheet.
Students learning basic Mendelian genetics can practice assigning genotypes and identifying heterozygous and homozygous configurations. Squares are set up to do crosses with purple and white flowers as seen in Mendel’s pea plants. The worksheet is very simple, designed for beginning students of biology and genetics. More difficult versions of genetics practice problems might…
This activity is a good starter for genetics units. Students are often fascinated by traits that are visible. Lively discussions of human genetics will often include students asking tons of questions about what they view as “oddities.” Though, many of those traits would be difficult to establish as strictly genetics, it provides a good…
