Answer :

The correct answer is option d.

“Peas have characteristics that have two forms” was the reason for Gregor Mendel to use peas in his experiment.

Explanation :

Johann Gregor Mendel was a botanist who conducted a “hybridization experiment” to study the genetic disparity and inheritance. For his work, he chose a pea plant. The pea plant scientifically is known as Pisum sativum. Mendel preferred pea plant for his “hybridization experiment” because the pea has two form characteristics and they are capable of self fertilization.

Further explanation :

All the seven traits of the Pisum sativum are in two forms, that Mendel was successful in manipulating. The seven traits were:

Pea shape that was either round or wrinkled. Pea colour that was either green or yellow. Pod shape that was either constricted or inflated. Pod shape that was either green or yellow. Flower Colour that was either purple or white. Plant size that was either tall or dwarf. Position of flowers that was either axial or terminal.

One trait was a dominant trait and the other was a recessive trait.

His experiment gave him three results or the laws of inheritance as per him.

1. Law of Dominance- It tells that in the cross of two parents with complementary traits, the brood will show the trait of one parent only, the dominant trait.

2. Law of Segregation- It describes the principle of individual traits being inherited.

3. Law of Independent Assortment- It states that an allele received by the gamete for one gene is not influenced by the allele received for any more genes.

Peas have characteristics that have two forms.

Further Explanation:

Gregor Mendel Was born in German-speaking family and he gained recognition as the founder of the modern science and genetics. He conducted pea plant experiments which he conducted between the period of 1856 and 1863 and his this experiment established many rules of heredity which are now known by the names of ‘Laws of Mendelian inheritance’.

He conducted hybridization experiments that were conducted on around 29000 pea plants. Mendel always chose peas for his experiments because he found Peas to be ideal choice because had easily observable traits which were 7 of which he could manipulate. He started his experiments on peas on two conditions and the first condition among them was that it possesses constant differentiating characteristics and hybrids of pea plants during the period of flowering were to be protected from the influence of all foreign pollen.

Read this excerpt from "hope, despair and memory" and answer the question. and yet it is surely human to forget, even to want to forget. the ancients saw it as a divine gift. indeed if memory us to survive, forgetting allows us to go on living. how could we go on with our daily lives, if we remained constantly aware of the dangers and ghosts surrounding us? the talmud tells us that without the ability to forget, man would soon cease to learn. without the ability to forget, man would live in a permanent, paralyzing fear of death. only god and god alone can and must remember everything. which of the following is true about the above excerpt? ethos is used in reference to “dangers and ghosts.” logos is used in saying all men forget and want to forget, because the talmud also praised forgetting. ethos is used in referring to the ancients, the talmud, and god. pathos is used without loaded language.
