During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has white flowers. The plant

s that result from this cross in the F1 generation have both purple and white flowers. What can the scientist conclude?
White flowers are dominant over purple flowers.
Neither purple flowers nor white flowers are dominant.
The plants in the P generation were not true-breeding.

The plants in the p generation were not true breeding. If they were, all of the flowers in the F1 would be purple or white, depending on which was dominant. You would then see an appearance of the recessive phenotype/genotype in the F2 generation.

Answer:

The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.

Explanation:

Meiosis is a type of cell division which is involved in the formation of haploid gametes.

During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.

During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.

Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
