Explain with example. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Even if a character shows multiple allelism, an individual will only have two alleles for that character. Why? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Discuss the genetic basis of wrinkled phenotype of pea seed. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation In our society a woman is o|ten blamed for not bearing male child. Do you think it is right? Justify. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation A, B, D are three independently assorting genes with their recessive alleles a, b, d, respectively. A cross was made between individuals of Aa bb DD genotype with aa bb dd. Find out the type of genotypes of the off spring produced. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation For the expression of traits genes provide only the potentiality and the environment provides the opportunity. Comment on the veracity of the statement. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation In a monohybrid cross of plants with red and white flowered plants, Mendel got only red flowered plants. On self-pollinating these F1 plants got both red and white flowered plants in 3:1 ratio. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation How are alleles of particular gene differ from each other? Explain its significance. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation “Genes contain the information that is required to express a particular trait.” Explain. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation In order to obtain the F1 generation, Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But for getting the F2 generation, he simply self-pollinated the tall F1 plants. Why? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation The pedigree chart given below shows a particular trait which is absent in parents but present in the next generation irrespective of sexes. Draw your conclusion on the basis of the pedigree. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation A person has to perform crosses for the purpose of studying inheritance of a few traits/characters. What should be the criteria for selecting the organisms? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Enlist the steps of controlled cross pollination. Would emasculation be needed in a cucurbit plant? Give reasons for your answer. 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Do you think Mendel’s laws of inheritance would have been different if the characters that he choose were located on the same chromosome? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation What is the cross between the progeny of F1 and the homozygous recessive parent called? How is it useful? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group respectively. What would be the genotype of both mother and father? 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation In the F2 generation of a Mendelian dihybrid cross, the number of phenotypes and genotypes are 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Two genes ‘A’ and ‘B’ are linked. In a dihybrid cross involving these two genes, the F1 heterozygote is crossed with homozygous recessive parental type (aa bb). 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation It is said that Mendel proposed that the factor controlling any character is discrete and independent. His proposition was based on the 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation The inheritance pattern of a gene over generations among humans is studied by the pedigree analysis. Character studied in the pedigree analysis is equivalent to 3 years ago Shilpi98 class 12 cbse ncert exemplar principles of inheritance variation Page 2 / 5 Prev 1 2 3 4 5 Next Share: Super Globals Requests: Server: Options and Features route: community use_home_url: url: https://eanshub.com/community/ pageid:187 default_groupid: 3 2022 How Can We Help?
