During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has white flowers. the plants that result from this cross in the f1 generation have both purple and white flowers. what can the scientist conclude?
a. white flowers are dominant over purple flowers.
b. neither purple flowers nor white flowers are dominant.
c. the plants in the p generation were not true-breeding.
d. all the plants in the f2 generation will have purple flowers.

Answer: Option c -the plants in the p generation were not true-breeding.

Explanation:

A true breeding plant is defined as the one which when self-fertilized results in offspring having the same traits as the parents. In simpler terms, the true breeding plants are homozygous in nature, that is they carry the same alleles for a particular gene.Since, on crossing the pea plant with purple flower and the pea plant with white flowers, the f1 generation had both purple and white colored flowers, this indicates that the parents were not true breeding because if that would have been the case then the flowers produced would have only shown one color (dominant trait). An image of the cross that took place between the two plants which were not true breeding and thus, resulted in both purple and white flowers is attached.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
