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>

a. vitamin d and vitamin b12
Explanation:
Vitamins are groups of organic compounds that are essential in small quantities for healthy human growth, metabolism, development, and body function. Vitamins are found in plants and animal foods or sometimes produced synthetically. Deficiencies of specific vitamins produce specific disorders. Vitamin d and vitamin b12 are important vitamins that the body needs. The body produces vitamin D when the skin is exposed to sunlight and it is very essential for strong bones, while vitamin b12 is naturally present in meats. Deficiency of vitamin d in the body can result in bone problems (including teeth) and it has also been linked to depression. Vitamin b12 deficiency can also affect mental functions by causing disorientation, memory loss, depression and confusion.
From the question, the elderly woman may be developing a deficiency of vitamin d and vitamin b12.
