In pea plants, round pea texture is dominant over wrinkled texture. How can you obtain true-breeding pea plants
having round peas with the least amount of work?
a. Cross plants having round peas with plants having wrinkled peas. Select round pea plants from the progeny because they are now true-breeding. b. Cross plants having round peas with other plants having round peas. Do this for multiple generations. c. Cross plants having round peas with plants having wrinkled peas. Select round pea plants from the progeny and do a testcross to determine which parental plants were homozygous dominant. d. Cross plants having round peas with plants having wrinkled peas. This will tell you which round pea plants are homozygous dominant and are thus true-breeding. e. It's not possible. You can only get true-breeding plants that have wrinkled peas.
In poultry, rose comb is controlled by a dominant allele, and its recessive allele controls single comb
(a) Give the genotype and phenotype produced from crossing a pure-breeding rose comb chicken with a pure-breeding single comb chicken. (b) Give the results of the backcross of the F1 hybrid with both pure-breeding parents. What will be an ideal response?
