Answer:
Cross an individual of the F1 with the purebred red flower, round pollen sweet pea parental.
Explanation:
The parental individuals are:
- PL/PL: purebred purple flower, long pollen sweet pea
- pl/pl: pure-bred red flower, round pollen sweet pea
The resulting F1 of the cross between the different parental types can only be PL/pl, which has purple flowers and long pollen. <u>This means that the purple flower (P) and long pollen (L) traits are dominant</u>.
To determine the recombination frequency between genes P/p and L/l, the cross should be done between a heterozygous individual for both genes (the F1) and a homozygous recessive individual for both traits (the pl/pl parental). <u>This is called a test cross.</u>

<h2>Weathering and erosion</h2>
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion
