In sweet pea plants, an allele for purple flowers (P) is dominant to an allele for red flowers (p). Additionally, an allele for long pollen grains (L) i dominant over an allele for short plan grains (l). Geneticist crossed plants that were heterozygous for both traits (PpLl X PpLl). What is the probability of producing plants with purple flowers and short pollen grains? 3/16 3/16 9/16 9/16 1/2 1/2 1/16

P(purple, short) = 3/16

Explanation:

Purple flowers require genotypes Pp, pP or PP

Short pollen grains require genotype ll

The genotypes are

PPll (1/16), Ppll (1/16), pPll (1/16) for a total of 3/16

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
