Dihybrid Crosses (Amoeba Sisters)

Dihybrid crosses genetics worksheet for mastering Punnett squares and predicting offspring traits!

How many traits are we examining in a dihybrid cross? 1 2 3 A cat that likes sinks must have at least 1 "S" dominant allele. True False What arethe genotypes for cats with hair?Select ALLcorrect answers. hh Hh HH What is the genotype of a cat loves sinks and has hair and is heterozygous for both traits? hhss HHSS HhSs Hhss What is the genotype of a hairless cat who hates sinks? HhSs hhss HHSs hhSs For each trait, how many alleles do the gametes carry? one two three What do the letters on the top and the side of Punnett square represent? possible haploid gametes probable diploid gametes Which of the following are NOT gametes the first cat parent can make? Hs ss hs hS What phenotype is Hhss? hairy and NO sinks hairy and loves sinks hairless and NO sinks hairless and loves sinks Punnett squares are used to Predict possible outcomes of a cross Determine the real genotypes of offspring
