PLZ HELP THANK U
In Figure 9.3 below is a cell that represents the following conditions: diploid, two homologous pairs of chromosomes, two unlinked
genes called R and A; cell is heterozygous for both genes.
What is the genotype of this cell?
R is the gene for tongue-rolling, as used in the previous examples. A determines arch
characteristics. A person who has the dominant allele has normal arches. An individual
who is homozygous recessive has flat feet.
What is the phenotype of the individual represented by the cell in Figure 9.3?
3. Recall that when this cell undergoes meiosis, each gamete receives one member of each homologous pair. List the possible
combinations of alleles that will be found in the gametes.
4.
In what proportion would you expect these gametes to occur?
