The pea plant was an ideal plant for Gregor Mendel’s experiments for several reasons. Pea plants are easy to artificially cross and easy to control self-pollination. They also have lots of offspring which allows for a large sample size to get more accurate results.
Why was the pea plant an ideal plant for 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. Furthermore, pea plants grow quickly, so he could complete many experiments in a short period of time.
Why did Mendel choose pea plants for his experiments quizlet?
Why did Mendel choose pea plants for his genetic experiments? Because the reproduce quickly and he could easily control how they mate; pea plants self pollinate and he was able to interrupt the self fertilization process and mate plants with plants that he wanted.
Which was more important to Mendel’s success his approach or his choice of experimental material?
This allowed him to easily observe the pattern of inheritance and compare the results of experiments with different traits for the reliability of results. Thus, his approach to studying one trait at a time was the main reason for his success among the given choices. Thus, the correct answer is option D.
What was Mendel’s model system?
Mendel carried out his key experiments using the garden pea, Pisum sativum, as a model system. Pea plants make a convenient system for studies of inheritance, and they are still studied by some geneticists today. Useful features of peas include their rapid life cycle and the production of lots and lots of seeds.
Why was it important that the pea plants Mendel used did not self-pollinate quizlet?
Why is the fact that pea plants can cross-pollinate and self-pollinate a key factor in Mendel’s work? Self-pollinating was important because it allowed Mendel to grow true-breeding plants. Cross-pollination was important because he could mix different traits to check results.
What conclusion did Mendel draw from his experiments with pea plants?
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.
Is a pea plant shows a recessive phenotype?
The “round or wrinkled” and “yellow or green” traits of pea seeds represent the simplest cases of Mendelian inheritance, where the diploid genotypes AA and Aa ( or the equivalent aA) give a dominant phenotype, and only the genotype aa gives a recessive phenotype.
What characteristics did Mendel study in pea plants?
Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
Why was Mendel successful with genetic experiments?
Using a simple organism like the garden pea, Mendel was able to control pollination among his experimental plants, and most importantly, he used true breeding plants with easily observable characteristics, such as flower color and height.
Which of the character is dominant in pea plant?
So, the correct answer is ‘green pod‘.
What are the 7 characteristics of pea plants?
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)
What could have happened if Mendel did not study pea plants quizlet?
If Mendel had not used true breeding plants then he would have seen much more variation in traits . He would not have been able to tell which traits were dominant or recessive because there would not have been reproducible ratios.
How did Mendel get the peas to cross fertilize quizlet?
What step did Mendel take to be sure that his pea plants cross-pollinated? He removed the anthers of one plant. What happens when a true-breeding plant self-pollinates? All of its offspring have the same traits as the parent.
What kind of plants did Mendel Discover would produce offspring identical to themselves when allowed to self pollinate?
Pea plants normally reproduce by self-pollination. What is true about Gregor Mendel’s peas? If the plants are allowed to self-pollinate, they would produce offspring identical to themselves.
How is the phenotype of a pea plant different from its genotype?
An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
Why would a pea plant that is heterozygous for the tallness trait have the dominant phenotype?
A heterozygous tall plant will have a genotype of Tt. T is mainly the dominant allele and will actually rule over the t allele, which is recessive. Therefore, due to the presence of the T allele, the plant will show a tall phenotype. Hence, the tall phenotype will be observed in a heterozygous tall pea plant.
How do you determine if a plant is homozygous or heterozygous?
Homozygous plants have two identical copies of a single gene. Heterozygous plants have two copies of a single gene, but those copies are alleles, or different versions of that gene. The second type is heterozygous. Plants that are heterozygous for a particular gene have one copy each of two different alleles, ‘Aa’.
What are the characteristics of pea plant?
The characteristics of a pea plant are:
- Colour of seed (green or yellow)
- Shape of seed (round or wrinkled)
- Colour of pod (green or yellow)
- Shape of pod (constricted or inflated)
- Size of the plant (tall or dwarf)
- Position of flowers (axial or terminal)
- Colour of flower (purple or white)
What happens when pea plants showing two different characteristics?
When pea plants with round and green seeds are crossed with wrinkled and yellow seed (both pure line), FI generation plants have round and yellow seed.
What are the 7 characteristics of pea plants?
There were 7 characters of the pea plant which were selected by Mendel for the experiments. The characters which were chosen by Mendel for his study were stem height, flower colour, flower position, pod shape, pod colour, seed shape, seed colour. All these characters belong to different chromosomes in the pea plant.
