What are the 7 traits Mendel studied on 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)
How many characteristics did Mendel investigate in pea plants?
seven different characteristics
Why do the seven characteristics Mendel studied in peas assort independently?
Genes located on different chromosomes will be inherited independently of each other. Mendel observed that, when peas with more than one trait were crossed, the progeny did not always match the parents. This is because different traits are inherited independently – this is the principle of independent assortment.
Why do Mendel choose pea plant for his experiment?
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 plant for inheritance?
He chose pea plants because they had easily observable traits. The Law of independent assortment states that the inheritance of one character is always independent of the inheritance of other characters within the same individual.
Why did Mendel’s work go unnoticed?
So why were his results almost unknown until 1900 and the rediscovery of the laws of inheritance? The common assumption is that Mendel was a monk working alone in a scientifically isolated atmosphere. His work was ignored because it was not widely distributed, and he didn’t make an effort to promote himself.
What was the most significant conclusion that Gregor Mendel drew from his experiments with the pea plants?
) What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units, and are not the results of “blending.”
Why did Mendel study pea plants quizlet?
Mendel studied pea plants because they reproduced sexually and had traits that were easily observable. A pair of factors (known as genes) control traits. One gene comes from each parent for every trait. Each trait is passed from generation to generation.
What did Mendel test with pea plants quizlet?
Mendel studied how traits are passed along to offspring. He used pea plants for 2 main factors: – Easy to grow and produce a large amount of offspring. – Self pollinate/Mendel could also cross pollinate.
What did Mendel test with pea plants?
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. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
What did Mendel learn about his pea plants?
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.
What was the main aim of Mendel’s experiment?
The main aim of Mendel’s experiments was: To determine whether the traits would always be recessive. Whether traits affect each other as they are inherited. Whether traits could be transformed by DNA.
What 3 conclusions were made after Mendel’s experiment?
—and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided an alternative to blending inheritance, the dominant theory of the time), and the Law of …
What was Gregor Mendel’s nickname?
Father of modern genetics
Who was Gregor Mendel’s family?
Anton Mendel
What are Mendel’s 4 principles?
The Mendel’s four postulates and laws of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
What are the three steps of Mendel’s experiments?
There were three major steps to Mendel’s experiments: 1. First he produced a parent generation of true-breeding plants. He made these by self-fertilizing the plants until he knew they bred true to the seven traits….F2 Generation.

What are the 7 traits that Mendel experimented?
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).
What are Mendel’s factors called today?
Mendel’s “factors” are now known to be genes encoded by DNA, and the variations are called alleles.
What does it mean for a pea plant to be true breeding?
Mendel’s Crosses The result is highly inbred, or “true-breeding,” pea plants. These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding.
What were the results of Mendel’s experiments?
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 independently of other traits and in dominant and recessive patterns.
What was Mendel’s first experiment?
In his first experiment, Mendel cross-pollinated two true-breeding plants of contrasting traits, such as purple and white flowered plants. The true-breeding parent plants are referred to as the P generation (parental generation).
What observations did Mendel make during his experiment?
Answer: During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms . 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.
What happened to the green trait in Mendel’s pea plants?
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. Green happens when a gene that turns on chlorophyll-degrading genes isn’t working. Which makes explaining why yellow is dominant a bit easier.
