The 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?Zero400100200

Two true breeding parents are crossed similar to Mendel's P generation. A tall plant is crossed with a short plant. What is the expected outcome for the F1 generation?*1 pointall tallall shorthalf tall, half shortall medium heigh

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

T = tall and t = shortA homozygous dominant tall pea plant is crossed with a heterozygous  pea plant. This cross would result in the following phenotype(s) of the offspring: Group of answer choices100% tall100% short75% tall and 25% short50% tall and 50% short

The height of pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). Which of the following is the genotype of a homozygous dominant pea plant?TtttTXTT 4

A cross between two pea plants that are hybrid for a single trait produces 60 offspring. Approx- imately how many of the offspring would be expected to exhibit the recessive trait? (1) 15 (2) 45 (3) 30 (4) 60
