Your question: When Gregor Mendel crossed a purple flowered pea plant with a white flowered pea plant?

Mendel noted the ratio of white flowered plants to purple-flowered plants was about 3:1. That is, for every three purple-flowered plants, there was one white flowered plant. Figure below shows Mendel’s results for the characteristic of flower color.

When Gregor Mendel crossed true-breeding purple flowered plants with true-breeding white-flowered plants Why were all the offspring purple?

Which was true of every offspring of this cross? They would be all purple because purple is the dominant trait and it blocks out the white recessive trait. A cross between two pink camellia plants produced the following offspring: 7 plants with red flowers, 7 with white flowers, and 14 with pink flowers.

When Mendel crossed pea plants with white flowers and purple flowers What color were the flowers of the F1 generation?

Figure 2. In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation). The resulting hybrids in the F1 generation all had violet flowers.

What were the results of Mendel’s first cross between a purple flower and a white flower plant?

As shown in Figure below, Mendel cross-pollinated purple- and white-flowered parent plants. … The F1 generation results from cross-pollination of two parent (P) plants, and contained all purple flowers. The F2 generation results from self-pollination of F1 plants, and contained 75% purple flowers and 25% white flowers.

What happened in Mendel’s first experiment when he crossed plants that had purple flowers with plants that had white flowers?

He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation. This law states that each characteristic is controlled by two factors, which separate and go to different gametes when an organism reproduces.

When Mendel crossed true-breeding purple flowered pea plants with true-breeding white flowered pea plants What was the outcome?

When Mendel crossed a true-breeding purple-flowered pea plant with a true-breeding white-flowered pea plant, he observed that all of the F1 offspring had purple flowers. When these F1 plants were selfed, he found 3/4 were purple and 1/4 were white.

When Mendel crossed true-breeding purple flower pea plants with true-breeding white flower pea plants What happened to the white flower trait?

Mendel discovered that by crossing true-breeding white flower and true-breeding purple flower plants, the result was a hybrid offspring. Rather than being a mix of the two colors, the offspring was purple flowered.

What happened when Mendel crossed 2 true-breeding white pea plants?

Mendel also experimented to see what would happen if plants with 2 or more pure-bred traits were cross-bred. He found that each trait was inherited independently of the other and produced its own 3:1 ratio. This is the principle of independent assortment. Find out more about Mendel’s principles of inheritance.

How did Mendel cross pollinate pea plants?

Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.

What was Gregor Mendel pea plant experiment?

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Why was pea plant used by Mendel?

To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). For example, pea plants are either tall or short, which is an easy trait to observe. … Mendel also used pea plants because they can either self-pollinate or be cross-pollinated.
