What did Mendel discover in his pea experiment?
Table of Contents
Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F1 offspring that all expressed one parent’s traits. The traits that were visible in the F1 generation are referred to as dominant, and traits that disappear in the F1 generation are described as recessive.
What Did Mendel’s experiments with pea plants show?
By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed. Mendel’s insight greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods.
What 7 traits did Mendel study in peas?
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)
Is green dominant or recessive in peas?
Mendel’s experiments showed that green is the recessive seed color in pea plants.
When did Mendel experiment on peas?
Though farmers had known for millennia that crossbreeding of animals and plants could favor certain desirable traits, Mendel’s pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity, now referred to as the laws of Mendelian inheritance.
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. Furthermore, pea plants grow quickly, so he could complete many experiments in a short period of time.
Why were pea plants used by Mendel?
Studying traits in peas Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
How did Mendel control pollination in 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.
Why did Gregor Mendel use peas in his experiments?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
Why Mendel use pea plants?
Which one is recessive in pea?
Explanation: Mendel based his experiments on pea plants and studied seven pairs of contrasting traits. Yellow seed colour is the dominant trait and green seed colour is the recessive trait.
What are Mendel’s pea plant experiments?
1. Mendel’s Pea Plant Experiments In this virtual investigation you will perform many of the same genetic crosses as Gregor Mendel. You will study the heredity of four pea plant characteristics by doing parental (P) and first generation (F1) crosses. In this activity, you should assume that the parental crosses are true-breeding plants.
What causes the wrinkled-seed character of Pea described by Mendel?
The wrinkled-seed character of pea described by Mendel is caused by a transposon-like insertion in a gene encoding starch-branding enzyme. Cell, 60: 115-122, 1990. « Previous Event | Next Event » Last updated: April 22, 2013

What did Erving Mendel study?
Mendel was a monk in the Augustinian order, long interested in botany. He studied mathematics and science at the University of Vienna to become a science teacher. For eight years, starting in 1857, he studied the peas he grew in the garden of his monastery.
