Mendel’s gene involved in pea color decides whether the chlorophyll in the pea will be broken down and degraded. When this gene isn’t working, the chlorophyll stays around and the pea is green. So in this case the recessive trait is indeed due to a broken gene.
What happened when Mendel crossed yellow and green pea plants?
Mendel crossed true-breeding plants having yellow peas with plants having green peas. The resulting plant had all yellow peas. An F1 cross resulted in 3/4ths of the plants having yellow peas and 1/4th of the plants having green peas.
Why did Mendel use green peas?
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: presence of observable traits with contrasting forms. produces many offspring in one cross. short life cycle.
What traits did Mendel study in pea plants?
During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.
Is green pea dominant or recessive?
recessive
Mendel’s experiments showed that green is the recessive seed color in pea plants.
What happened when Mendel let the yellow peas self fertilize?
Mendel instead observed that all the offspring of the cross were tall, and that when they self-fertilized, they produced tall and short plants in a ratio of 3:1.
What happen when pea plant showing two different characteristics?
Answer. Answer: If the inheritance of more than one pair of characters is studied simultaneously the factors of genes for each pair of characters sort out independently.
What happened when Mendel crossed two traits of a character in a pea plant?
Answer: 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 .
What happened in Mendel’s first experiment?
Mendel’s First Set of Experiments. Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color. As shown in the Figure below, Mendel cross-pollinated purple- and white-flowered parent plants.
Why was it important for Mendel to remove the anthers from pea plants in his experiments when crossing two different true breeding pea plants?
Why was it important for Mendel to remove the anthers from pea plants in his experiments when crossing two different true-breeding pea plants? You have an F2 generation derived from two true-breeding parents with different characteristics for the same trait (determined by a single allele).
What Did Mendel’s experiments with pea plants show?
In 1865, Mendel presented the results of his experiments with nearly 30,000 pea plants to the local natural history society. He demonstrated that traits are transmitted faithfully from parents to offspring in specific patterns.
What color was recessive with the pea plant experiment?
white flower colour
Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked.
What color is dominant in pea plants?
In pea, yellow seed colour is dominant over green colour. Heterozygous yellow seeded plant is crossed with green seeded plant.
How could a pea plant that has a recessive allele for green peas show the yellow pea phenotype?
If a pea plant has a recessive allele for green peas, it will produce: Green Peas if it does not also have a dominant allele for yellow peas.
What are the seven traits of pea plants that Mendel worked with?
On the next screen, he reveals that there are seven different traits:
- Pea shape (round or wrinkled)
- Pea color (green or yellow)
- Pod shape (constricted or inflated)
- Pod color (green or yellow)
- Flower color (purple or white)
- Plant size (tall or dwarf)
- Position of flowers (axial or terminal)
Why was Mendel successful in his experiment performed on pea plant?
Complete answer: Mendal was successful to explain the laws of heredity because he chose pea plants that were pure. The main reason for the success of Mendel was that he took one character at one time in his experiments of hybridization.
Which of the following characteristics of pea plants was not used by Mendel in his experiments?
Mendel chose Pisum sativum (pea plant) for his experiments. He selected seven traits of pea plant. It excludes plant colour. He chose characters like flower colour, flower position, stem length, seed shape, seed colour, pod shape and pod colour.
What type of inheritance is shown when a round seed shape of pea plant is crossed with wrinkled?
Given an inheritance pattern of dominant–recessive, the genotypic and phenotypic ratios can then be determined. In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas.
How did Mendel explain the inheritance of traits?
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 did all of the F1 offspring of Mendel’s purple and white flowered pea cross always look like one of the two parental varieties?
Why did the F1 offspring of Mendel’s classic pea cross always look like one of the two parental varieties? One phenotype was completely dominant over another.
Which among the following characters selected by Mendel in a pea plant is a recessive character?
Complete answer: Green cotyledon colour was one of the recessive traits studied by Mendel in garden pea.
