In the mid-1800s, an Austrian monk named Gregor Mendel Opens in modal popup window began his own experiments with plants. Unlike his predecessors, he used rigorous scientific methods in his experiments.

Mendel conducted his experiments with pea plants, which he grew in the garden of his monastery. The plants are easy to grow, reproduce quickly, and have several distinct characteristics Opens in modal popup window , or features, that are easy to observe. Characteristics of pea plants include flower color, seed color, and pea pod shape.

<span>Moreover, Mendel knew that each characteristic exists as one of two traits Opens in modal popup window , or forms of the character. For example, the seed color characteristic exists as one of two traits: green or yellow.</span>

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed
STALIN [3.7K]

<u>Answer:</u>

Although statements are not given in the question, we could make the most possible deduction as follows:

The allele for purple flowers is dominant whereas allele for white flowers is recessive.

<u>Explanation:</u>

According to the question,

  1. Purple flower plant was crossed with white flower plant.
  2. All offsprings have purple flowers.

Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
