Question

Principles of Complete the Punnett square for the following parental cross List the possible phenotypes and genotypes for each cross Each parent is heterozygous for tongue rolling Rr Rolling is considered dominant over non rolling The cross is written Rr x Rr Each parent can contribute two types of gametes Half of the gametes carry the R allele and half carry the r allele To fill in the square write the alleles that one parent can contribute along the side of the Punnett square Then combine the alleles from both parents inside each box The combinations of all alleles inside the boxes are the possible genotypes of the offspring Keep in mind that a Punnett square tells you the probable proportions of offspring genotypes not the guaranteed outcome Female R r What is the genotype of the mother What is the phenotype of the mother List all possible offspring phenotypes List all possible offspring genotypes What is the probability of getting tongue rollers R father father Male
