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: – quick and easy to grow and several peas are produced in each pod.
Why was the garden pea ideal for performing Mendel’s experiments?
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 garden peas a good choice for a study of heredity quizlet?
The pea plant was ideal for several reasons. They had traits that were easy to track from generation to genereation. Each trait has 2 froms. It is easy to grow and matures quickly.
Why did Mendel specifically chose pea plants as the subjects in his experiments quizlet?
Mendel first self-pollinated tall pea plants: Mendel noticed that only tall plants were produced. He concluded, that the tall pea plants must contain a factor for tallness. Mendel then self-pollinated short pea plants: This resulted in only short pea plants.
Why did Gregor Mendel use peas in his experiments quizlet?
Mendel studied pea plants because they reproduced sexually and had traits that were easily observable.
What are the advantages of using pea plants to study genetics?
What were the advantages of using pea plants for genetic studies? Peas can be “true-breeding” meaning that their offspring are identical to the parent plant. This species reproduces fast and makes many offspring, and self-breeding is easy to prevent by cutting off the stamens of the flowers.
Which of the following are features that made the pea A good model organism for studying inheritance?
Mendel’s garden pea had the following characteristics that made it a good model organism:
- rapid reproduction (large number of individuals produced in a short time);
- self-fertilization (due to possibility of both egg and pollen coming from same plant), or preventing self-fertilization;
- pure inbred lines (ex., purple vs.
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 did Mendel observe when he performed a Dihybrid cross in pea plants quizlet?
When Mendel examined the inheritance of two traits in a dihybrid cross in pea plants, he observed that both traits were always transmitted together to the offspring.
What were the results of Mendel’s experiment quizlet?
Mendel concluded that traits are passed from one generation to the next by inheritance factors.
Why did Gregor Mendel choose pea plants?
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. Self-pollination happens before the flowers open, so progeny are produced from a single plant.
Why did Gregor Mendel use pea plants as a model for genetics?
Mendel was curious about how traits were transferred from one generation to the next, so he set out to understand the principles of heredity in the mid-1860s. Peas were a good model system, because he could easily control their fertilization by transferring pollen with a small paintbrush.
What are four advantages of Mendel’s pea plant model?
Its short life cycle made it possible to study several generations within a short period. (v) It is easy to cultivate. (vi) It is easy to cross because pollen from one plant can be introduced to the stigma of another plant. The flower and fruit of garden pea A.
What are the seven characteristics of garden pea observed by Mendel?
Gregor Mendel cross-bred peas which had 7 pairs of pure-bred traits, which are as follows:
- Colour (green or yellow)
- Shape (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 was Mendel’s experiment with pea plants?
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 traits did Mendel study in pea plants?
Mendel studied the inheritance of seven different features in peas, including height, flower color, seed color, and seed shape. To do so, he first established pea lines with two different forms of a feature, such as tall vs. short height.
How was Mendel able to cross pollinate his pea plants and keep them from self pollinating?
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 does it mean when pea plants are described as being true-breeding quizlet?
What does it mean when pea plants are described as being true-breeding? if the plants are allowed to self-pollinate, they would produce offspring identical to themselves. You just studied 12 terms!
How did Mendel get the peas to cross fertilize quizlet?
Why was it a key factor in Mendel’s work that peas can both cross-pollinate and self-pollinate? Self-pollination allowed him to grow true-breeding plants and Cross-pollination could allow him to mix different traits and check the results.
Which one is the dominant character in plant garden 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.
How did Mendel control pollination in pea plants quizlet?
How did Mendel control pollination in pea plants? 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. Describe in general terms Mendel’s first set of experiments.
