Question

For the first character (seed shape), determine which trait was dominant. (1 pt)

b) Justify your selection by referencing two pieces of evidence from the data table. (1 pts)
c) Specify the genotype of the F, generation for the seed shape character as being either homozygous or heterozygous. (1 pt)
d) Justify your selection by referencing evidence from the data table,

Answer 1

a) The dominant trait for seed shape is round.

b) Two pieces of evidence from the data table that support this conclusion are:

All of the offspring in the F1 generation had round seeds, even though one parent had wrinkled seeds.

In the F2 generation, there were 547 plants with round seeds and 185 plants with wrinkled seeds. This is a ratio of approximately 3:1, which is the expected ratio for a monohybrid cross involving a dominant and recessive allele. c) The genotype of the F1 generation for the seed shape character is heterozygous. d) This can be justified by the fact that the F1 generation produced offspring with both round and wrinkled seeds. If the F1 generation was homozygous for the round seed allele, then all of the offspring would have round seeds.
