Answer and Explanation: Mendel’s cross-pollination of pea plants proved that genes of two separate organisms are passed to their offspring.
What Did Mendel’s experiments with pea plants show?
Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.
What Did Mendel’s cross-pollination of pea plants prove different offspring of the same parents inherit identical characteristics?
Principle of independent assortment
Mendel observed that, when peas with more than one trait were crossed, the progeny did not always match the parents. This is because different traits are inherited independently – this is the principle of independent assortment.
Why did Mendel perform cross-pollination experiment?
Since pea plants almost always self pollinate he could remove the anthers of the flowers he had selected and cross-pollinate by hand. This practice allowed him to have complete control over which plants were the parents, and the characteristics he was introducing and observing.
What was the purpose of Mendel’s experiment?
Mendel did not set out to conduct the first well-controlled and brilliantly-designed experiments in genetics. His goal was to create hybrid pea plants and observe the outcome. His observations led to more experiments, which led to unusually prescient conclusions.
What was Mendel’s conclusion from his experiments with the peas?
In 1865, Mendel presented the results of his experiments with nearly 30,000 pea plants to the local Natural History Society. He demonstrated that traits are transmitted faithfully from parents to offspring independently of other traits and in dominant and recessive patterns.
What was Mendel’s most significant conclusion from his research with pea plants?
Traits are inherited in discrete units
So, the correct option is ‘Traits are inherited in discrete units one from each parent‘.
What happens when pea plants showing two different characteristics?
When pea plants with round and green seeds are crossed with wrinkled and yellow seed (both pure line), FI generation plants have round and yellow seed.
What are the conclusions of Mendel experiment?
Upon compiling his results for many thousands of plants, Mendel concluded that the characteristics could be divided into expressed and latent traits. He called these dominant and recessive traits, respectively. Dominant traits are those that are inherited unchanged in a hybridization.
Why Mendel choose pea plant for his experiment Class 10?
Mendel selected pea plants for his experiments due to their easily detectable, contrasting characters. These are bisexual plants and grow to maturity in a single season only. In these plants, cross-pollination can also be done artificially.
Why did Mendel choose pea plant for his experiments give 4 reasons?
(i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iii) The different physical characteristics were easy to recognize and study. (iv) They have a shorter life span and are the plants that are easier to maintain.
How did Mendel prevent cross-pollination?
To perform his experiments, how did Mendel prevent pea flowers from self-pollinating and control their cross-pollination? He cut away the pollen-bearing male parts of a flower and dusted that flower with pollen from another plant.
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 are the important conclusions made by Mendel Make a list of these conclusions?
—and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided an alternative to blending inheritance, the dominant theory of the time), and the Law of
When did Mendel transfer pollen from one pea plant to another?
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. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination.
What was a conclusion Mendel drew from F1 generation of this cross?
What was a conclusion Mendel drew from the F1 generation of this cross? The dominant factor, or allele, is for round seeds.
Which is a dominant trait that Mendel observed in pea plants?
These plants would serve as the P1 generation for the experiment. In this case, Mendel crossed the plants with wrinkled and yellow seeds (rrYY) with plants with round, green seeds (RRyy). From his earlier monohybrid crosses, Mendel knew which traits were dominant: round and yellow.
Which among the following characters selected by Mendel in a pea plant is a recessive character?
Complete answer:
Green cotyledon colour was one of the recessive traits studied by Mendel in garden pea.
Which of the following is not a characteristic of the pea plants with which Mendel worked?
Answer and Explanation: The characteristic that was not displayed by Mendel’s pea plants was (e) they exhibited blending inheritance. One of the main reasons that Mendel started his experiments was to discredit the theory of blended inheritance (where offspring have a mix of the characteristics of their parents).
What did Mendel discover through his experiment?
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.
What was the conclusion from Mendel’s two factor crosses?
Mendel’s Conclusions
Each parent has a gene pair in each cell for each trait studied. The F1 from a cross of two pure lines contains one allele for the dominant phenotype and one for the recessive phenotype. These two alleles comprise the gene pair.
