Aunt Petunia is 2 plants.One has blue flowers and long leaves. The other has pink flowers and leaves short?
Aunt Petunia decides performing an experiment on plants. It passes through the plant with blue flowers and leaves along with the plant that has pink flowers and short leaves. All children have blue flowers and long leaves. She decides to cross 2 of the blue flower, long-leaved offspring with each other. a) Name the type of cross she carries. b) Assign letters to each allele – be sure to label what each letter represents. (capital letters indicate dominant alleles, and lowercase indicate recessive alleles) c) Give the phenotypic ratios expected from this type of cross. Be sure to include features with numbers.
a cross) dihybrid, because it looks at two features of a cross. b) the blue flowers are dominant, so that it is the allele B. Pink flowers are recessive, so it is allele b. long leaves are dominant, so it is allele L. short leaves are recessive so it allele is L. The heterozygous genotype of a flower with blue flowers and grass is BbLl. c) As in most dihybrid cross, the ratio is – 9: 3: 3: 1 9: blue flowers, long leaves. 3: Blue flowers, leaves short. 3: Pink flowers, leaves long. 1: Pink flowers, leaves short. Peace:)
