the flowers of the plant Antirrhinum are either white or red. Apure bred line of Antirrhinum with red flowers is crossed with apure bred line of Antirrhinum with white flowers and all the F1progeny have white flowers. The F1 progeny plants are inbred andthe F2 plants have either white or red flowers, in a ration of 13plants with white flowers to 3 plants with red flowers.

P pure bred line with red flowers X pure bred line with whiteflowers

F1 all plants have white flowers

F2 1300 plants with white flowers

300 plants with red flowers

A. Based on this dad you decide that a minimum of two geneticloci control flower color in Antirrhinum. Explain yourreasoing!

B. Call these two genetic loci A anda B. What are the genotypesof:

1. the F1 plants?

2. the F2 plants that have red flowers?

C. Based on this dad, propose a hypothetical biochemicalexplanation for the colors of the flowers in the F2 progeny.Explain your reasoning!

Any help would be appreciated!!!

A homozygous plant with 20 cm diameter flowers is crossed with a homozygous plant of the same species with 40 cm diameter flowers. The F1 plants all have 30 cm diameter flowers. In the F2 generation (N=512 plants), 2 plants have 20 cm diameter flowers and 2 plants have 40 cm diameter flowers. The rest of the plants have flowers ranging in sizes in between 20-40 cm in diameter.

(a) What frequency distribution of flower diameter do you expect to see in the F2 generation?

(b) What frequency distribution of flower diameter do you expect to see in the progeny of backcross between an F1 plant and the 40 cm diameter flowered parent?


explain the answers please. thank you
