- What are the three reasons the garden pea is a good subject for studying heredity? They are easy to grow, one cross produces many offspring.
- What are the three main steps for producing a monohybrid cross?
- Alleles.
- Dominant.
- recessive.
- homozygous.
- heterozygous.
- genotype.
Why were garden peas a good choice for a study of heredity quizlet?
Peas were an ideal choice for Mendel to use because they had easily observable traits there were 7 of which he could manipulate. Mendel planned to selectively cross pollinate the peas with one another to study the traits passed on and the results from each pollination.
What are two reasons peas make a good model system for studying heredity?
Peas were a good model system, because he could easily control their fertilization by transferring pollen with a small paintbrush. This pollen could come from the same flower (self-fertilization), or it could come from another plant’s flowers (cross-fertilization).
Why was the garden pea a good choice?
Why did Mendel choose common, garden-variety pea plants for his experiments? Pea plants are a good choice because they are fast growing and easy to raise. They also have several visible characteristics that may vary.
What are the 7 characteristics of pea plants?
What Are The 7 Characteristics Of Pea Plants?
- 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)
How Did Mendel’s studies contribute to the foundation of modern genetics?
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.
Can pea plants be artificially fertilized?
Pea Plant Pollination In order to study these characteristics, Mendel needed to control the pollination of the pea plants through artificial fertilization. In this way, Mendel controlled the characteristics that were passed onto the offspring. The product of cross-pollination is known as a hybrid.
Why was the garden pea a good choice as an experimental organism in Mendel’s work?
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 are peas a good model system for studying heredity 7 How did Mendel cross pollinate flowers?
Pea plants are naturally 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.
