What did Mendel discovery during his experiments

Expert Solution

Ans . 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.

The Mendel's law of inheritance are :-

1) Law of dominance :- It states that when two alleles of an inherited pair is heterozygous, then the allele that is expressed is dominant whereas the allele that is not expressed is recessive.

2) Law of segregation :- It states that the paired alleles separate or segregate during gamete formation. Consequently , each gamete would contain only one copy of every paired unit factors.

3) Law of independent assortment :- It states that the alleles of two ( or more ) different genes get sorted into gametes independently of one another . In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.

Mendel discovery during his experiments also include :-

(i) Characters are unitary. i.e. they are discrete.

(ii) Genetic characteristics have alternate forms , each inherited from one of two parents. These are known as alleles.

(iii) One allele is dominant over the other. The phenotype reflects the dominant allele.

(iv) Gametes are created by random segregation. Heterozygotic individuals produce gametes with an equal frequency of the two alleles.

1- What was one of the most significant conclusions that Gregor Mendel drew from his experiments with pea plants? Group of answer choices There is considerable genetic variation in garden peas. An organism that is homozygous for many recessive traits is at a disadvantage. Traits are inherited in discrete units and are not the results of "blending." Genes are composed of DNA. 2- In a testcross, an unknown individual was crossed with a homozygous recessive individual and 50% of the...

Mendel derived four principles of inheritance from his genetics experiments with pea plants. Explain these four postulates in your own words. Using the chromosomes pictured in Figure 2-10 on pages 22-23 in your textbook, relate his Law of Segregation and Law of Independent Assortment to your knowledge of meiosis. Be sure to describe the stages of meiosis that demonstrate these laws.

in his analysis of F2 individuals in his one-factor crosses, Mendel inferred the genotypes associated with dominant phenotypes by examining F3 produced by selfing the F2. You decide instead to test cross the dominant phenotype F2, crossing them to recessive parents. Because you are busy with classes, you examine only 8 progeny from each test cross to determine whether an individual F2 is pure breeding or hybrid like. What fraction of the dominant phenotype F2 would you identify as pure...
