Title: Draw one card from each pile, representing meiosis, and record the genotype resulting from ... Post by: vpgoranova on Jul 23, 2016 Monohybrid Cross Let the two colors of cards represent genes. Shuffle the deck well, then split it into two equal piles. One pile represents sperm, the other ova. Letting red cards represent dominant genes (R) and black cards represent recessive genes (r), you have represented parents containing Rr genes. What is your expectation or prediction of the variation possible in the offspring?
Draw one card from each pile, representing meiosis, and record the genotype resulting from fertilization. Keep a tally (IIII II) of at least 20 fertilizations, and complete the data table to show how your results compare to your expectations. Calculate the ratios as percents or decimals for easy comparison with the expected, predicted ratio. Genotype Tally Total Ratio Expected Phenotype Ratio Expected RR Rr rr Do your results match your expectations satisfactorily? |
