Big ! long stems (t) are dominant over short stems (t) for pea plants. determine the phenotypic and genotypic ratios of the offspring from the (hint: draw punnett squares, phenotypic ratios should be in the format similar to 1 long : 1 short and genotypic ratios should be in the form similar to 1 tt : 1 tt : 1 tt) be sure to reduce the ratios to lowest terms (for example, 2 : 2 reduces to 1: 1):
a) cross-pollination of a heterozygous long-stem plant with a short stem plant.
phenotypic ratio:
genotypic ratio:
b) self-fertilization of a heterozygous plant
phenotypic ratio:
genotypic ratio:
4. cystic fibrosis is regulated by a recessive allele, c. explain (do not just fill in the punnet square below) how two normal parents can produce a child with this disorder. be sure to include the genotype of a child with cystic fibrosis. (hint: give the genotypes of the normal parents and show that a cross is possible to result in a cystic fibrosis offspring).
