svp [43]
Given:
savings 12% of her salary.
savings $4,200
This year's salary: x + 3,000
Last year's salary: x

4,200 represents 12% of her salary.
4,200 / 12% =  35,000 is her salary this year.

You cross two true-breeding parents (one with purple flowers and one with white flowers). All of the F1 progeny (offspring) have
kogti [31]

Answer:

The correct answer is 375 purple flowers.

Step-by-step explanation:

If all the F1 generation from true-breeding parents are purple than the genotype would be heterozygous i.e., Pp and Pp. Here P indicates the dominant allele which produces purple flower and p indicates the recessive allele of white flower.

So if we will cross the F 1 generation than the genotype would be PP, Pp, Pp, pp. That means 3 out of 4 offspring would be purple because three genotypes out of four have dominant purple allele(P).

So if out of 4 flower 3 is purple than according to calculation out of 500 flower 375 offspring would be purple(3/4*500= 375). Therefore the correct answer is 375 purple flowers should be produced.
