When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, why was it impossible to observe segregation? A. Alleles for height do not segregate in the F2.

B. Alleles segregate only in the F2 generation.

C. Alleles segregate best when two tall plants are crossed.

D. Alleles in the F1 must be Tt to have height variety in the F2.

Answers

Answer 1
Answer: When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, it was impossible to observe segregation because D) alleles in the F1 must be Tt to have height variety in the F2.
Answer 2
Answer:

Answer:

Alleles in the F1 must be Tt to have height variety in the F2.

Explanation:

  • The law of segregation given by Mendel states that the pair of an allele for a given gene separate during the formation of gametes and then these gametes fuse randomly with each other during fertilization to determine the genotype of the individual.
  • Therefore, for a pure breeding tall plant, the alleles would form two gametes each having the allele T and for a pure breeding small plant, each of the gametes will have allele t.
  • Therefore, the only possible combination from TT X tt would be Tt and thus, segregation is not observed.

6. The amount of a crop that a farmer can harvest per acre is referred to as crop yield. Farmers have been able to increase their crop yield by adopting the use of genetically modified (GM) crops. What’s the general trend shown

Answers

The general trend shown is that the amount of crop that a farmer can harvest per year keeps increasing by adopting the genetically modified crops in the U.S. and it keeps growing steadily. If it keeps up the future of GM crops use will depend on the ability of the farmers to adopt best management practices and the acceptance of the consumer for products from GM sources.
