What are the genotypes of the f1 and f2 progeny

Reference no: EM1397116

The flowers of antirrhinum are either white or red. A pure bred line of Antirrhinum with red flowers is crossed with a pure bred Antirrhinum with white flowers and all of the F1 progeny have white flowers. The F1 progeny plants are inbred and the F2 plants have either white or red flowers, in a ratio of 13 plants with white flowers to 3 plants with red flowers.

1) Based on this data, you decide that a minumum of 2 (ie. Aa/Bb etc.) genetic loci control flower color in Antirrhinum. EXPLAIN your reasoning.

2) What are the genotypes of the F1 and F2 progeny?

3) Based on the data, propose a hypothetical biochemical explanation for the colors of the flowers in the F2 progeny. Again, explain your reasoning.
