What attributes of the garden pea plant made it?

What attributes of the garden pea plant made it?

what attributes of the garden pea plant made it an excellent organism for Gregor Mendel’s genetic studies? peas produce manyh offspring. the have traits that come in two forms, and crosses between the plants can be controlled. this is incomplete dominance.

Which of the following characteristics made the pea plant Pisum sativum an ideal organism for Mendel’s studies?

Which of the following characteristics made the pea plant Pisum sativum an ideal organism for Mendel’s studies? – It has the ability to self-fertilize.

How many chromosomes would you expect to find in its triploid offspring?

One set of chromosomes has 23 chromosomes. This is called a haploid set. Two sets, or 46 chromosomes, are called a diploid set. Three sets, or 69 chromosomes, are called a triploid set.

What is the blending theory of inheritance what observations led Mendel to question this theory?

Mendel noticed plants in his own garden that weren’t a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory.

What are the seven characteristics of pea plants that Gregor Mendel examined enumerate?

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 does Mendel choose pea plant?

Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iv) They have a shorter life span and are the plants that are easier to maintain.

What are the seven characteristics of garden pea observed by Mendel?

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)

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. Mendel also used pea plants because they can either self-pollinate or be cross-pollinated.

How do triploid plants reproduce?

Triploids, in particular, are characterized by the problems of chromosomal pairing and segregation during meiosis, which may cause aneuploid gametes and results in sterility. Thus, they are generally considered to reproduce only asexually. Fully sexualized worms begin reproducing by copulation rather than fission.

What are triploid plants?

Triploid plants have three sets of chromosomes, and many desirable characteristics, including greater vigor; broad, thick, dark green leaves; and larger flowers or fruit, which result in higher yield or higher harvest index.

What did Mendel discover about 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.

Why was the pea plant a good choice for Mendel?

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.

What did Mendel say about the color of pea plants?

When Mendel studied the color of the flowers on the pea plants (purple or white) he saw the same effect. The color of the flowers did not blend together – purple showed itself 75% of the time and white showed itself 25% of the time.

What are the characteristics of a pea plant?

Each characteristic has two common values. For example, seed form may be round or wrinkled, and flower color may be white or purple (violet). Mendel investigated seven different characteristics in pea plants. In this chart, cotyledons refer to the tiny leaves inside seeds. Axial pods are located along the stems.

How many pea plants did mitmendel study?

Mendel would end up growing and studying nearly 29,000 pea plants between 1856 and 1863.

Are pea plants easy to grow?

Easy to grow in the garden. The flowers of pea plants are hermaphrodite, i.e flowers have bisexual characteristics. The generation time of pea plants is less. They have excellent disease resistance and have an optimal rate of survival.
