In a plant, fruit color is either red or yellow, and fruit shape is either oval or long. Red and oval are the dominant traits. Two plants, both heterozygous for these traits, were testcrossed, with the results shown in the following table. Determine the location of the genes relative to one another and the genotypes of the two parental plants.
Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the difference in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aa bb cc) is 10 cm in height. The other strain (AA BB CC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce F2 progeny. Give the phenotypes and the expected proportions of the F2 progeny.

To study the phenotype associated with this trait, you cross a plant that is homozygous for the “long pod” allele with a pea plant that is homozygote for “short pod” allele. When measuring the length of the pods of the parents and resulting offspring, you obtain the following data: Plant Length (cm) Homozygous (“Wide” allele) 15 cm Homozygous (“Short” allele) 4 cm Resulting cross breed 9 cm What can you conclude about this phenotype/trait? Long and short alleles are codominant Wide allele shows incomplete dominance over the short allele Wide allele shows complete dominance over the short allele Short allele shows complete dominance over the long allele The wide and short genes are linkedarrow_forward
- Two gene loci, A and B, are on separate chromosomes and alleles A and B are dominant over alleles a and b. A codes for long branches, a codes for short branches. B codes for green leaves and b codes for blue leaves. A branch diagram or a punnett square would be useful for you to work this problem.
