Mendel described the parents he crossed to make his first generation of pea plants as being pure for each trait. Today we use the term homozygous instead of pure.Mendel’s first-generation pea plants with purple flowers had which set of alleles?A.Two alleles for purple flowersB.Two alleles for white flowersC.One allele for purple flowers and one allele for white flowersD.The alleles for flowers and the alleles for color

Mendel bred a purple-flowered pea plant with a white-flowered pea plant and found that all the offspring had purple flowers. But then when he bred together two of the purple-flowered offspring, some of their offspring had white flowers.Using the concepts of dominant and recessive alleles, explain how the trait of white flowers skipped a generation.

Sometimes, when Mendel crossed two pea plants with each other, he obtained a phenotypic ratio of 3:1 purple-flowered pea plants to white-flowered pea plants. These results are consistent with which set of parents?Multiple ChoiceHomozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and homozygous purple pea plantHeterozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and heterozygous purple pea plant

Assertion(A):- Mendel chose a no. of varieties of garden pea as plant for his experiments Reason(R):- Garden pea has well defined characters and was bisexual

In 1866, Mendel published three main conclusions to his findings. Which of the following ideas was not proposed by Mendel?Characteristics are determined by hereditary unitsHereditary units are organised in chromosomesHereditary units can be dominant or recessive Hereditary units are passed on unchanged by both parents3The height of Mendel’s pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). In a series of F1 crosses involving one homozygous tall plant (TT) and one short plant (tt), 400 F2 offspring were produced. Approximately how many of these offspring would you expect to be short?200Zero4001004In a series of crosses involving pea plants heterozygous for the height gene, 800 offspring are produced. Approximately how many of these offspring would you expect to be tall?8002006004005Mendel’s investigations were ‘reproducible’. What is meant by this term?The pea plants could be reproducedThe investigations could be repeated by different researchers with different resultsMendel reproduced his own investigations with the same results on numerous occasionsThe investigations could be repeated by different researchers with the same results

Select all of the reasons why pea plants were a good choice for Mendel to use in his heredity experiments.Multiple select question.They have traits that appear in two distinguishable forms.They produce few offspring.They grow slowly and consist of only 900 cells in the adult.They develop quickly.They can be cross-fertilized or self-fertilized.
