Most genetic traits have a stronger, dominant allele and a weaker, recessive allele. In an individual with a heterozygous genotype, the dominant allele shows up in the offspring and the recessive allele gets covered up and doesn’t show. This is called complete dominance.
This series of worksheets keys in on the prediction of hereditary trait transfer. They start with simple Punnett Squares and move to detecting complex Dihybrid traits. Get Free Worksheets In Your Inbox!
When an organism has the dominant phenotype, then its genotype can be either heterozygous or homozygous dominant (you can’t tell by looking at it). In order to find out we must do a test cross using an homozygous, recessive organism. For example: In Dalmatian dogs, the gene for black spots is dominant to the gene for liver colored spots. If a ...
In pea plants, round (R) is dominant to wrinkled (r). A heterozygous female is crossed with a wrinkled male. Make a Punnett Square to determine the possible offspring.
This worksheet covers the basics of Mendelian inheritance and Punnett squares. Practice problems, featuring traits from the Mutt Mixer interactive, give students a chance to apply each new idea.
Our Heredity lesson plan explores how traits pass through generations and how Punnett squares help us predict which traits things will have. Free PDF!
