A set of hermaphrodite self-crosses and male x hermaphrodite crosses were established, and the phenotypes of offspring were examined. Examine the following data set and the answer the subsequent questions: Crosses Strain 1: Left roller phenotype (hermaphrodite self-cross): 310 left roller offspring Strain 2: Right roller phenotype (hermaphrodite self-cross): 230 right roller, 80 normal offspring Strain 3: Normal phenotype (hermaphrodite self-cross): 330 normal offspring Strain 4: Normal phenotype (hermaphrodite self-cross): 235 normal, 78 left roller offspring Strain 1 Left roller phenotype hermaphrodite x Strain 3 normal male: 820 normal offspring Strain 2 Right roller phenotype hermaphrodite x Strain 3 normal male: 550 right roller, 548 normal offspring Strain 2 Right roller phenotype hermaphrodite x Strain 1 left roller male: 823 normal offspring For crosses involving hermaphrodites and males, reciprocal crosses yielded similar results. Create a possible explanation for these data, which accounts for the modes of inheritance observed and genotypes of these strains. Use allele symbols and text.

Question
A set of hermaphrodite self-crosses and male x hermaphrodite crosses were established, and the phenotypes of offspring were examined. Examine the following data set and the answer the subsequent questions:
Crosses
Strain 1: Left roller phenotype (hermaphrodite self-cross): 310 left roller offspring
Strain 2: Right roller phenotype (hermaphrodite self-cross): 230 right roller, 80 normal offspring
Strain 3: Normal phenotype (hermaphrodite self-cross): 330 normal offspring
Strain 4: Normal phenotype (hermaphrodite self-cross): 235 normal, 78 left roller offspring
Strain 1 Left roller phenotype hermaphrodite x Strain 3 normal male: 820 normal offspring
Strain 2 Right roller phenotype hermaphrodite x Strain 3 normal male: 550 right roller, 548 normal offspring
Strain 2 Right roller phenotype hermaphrodite x Strain 1 left roller male: 823 normal offspring
For crosses involving hermaphrodites and males, reciprocal crosses yielded similar results.
Create a possible explanation for these data, which accounts for the modes of inheritance observed and genotypes of these strains. Use allele symbols and text.
Expert Solution
Step 1: What is hermaphrodite?
A hermaphrodite is an organism that possesses both male and female reproductive organs within a single individual. This unique characteristic allows hermaphrodites to engage in both the production and fertilization of gametes, which are the specialized cells involved in reproduction, without the need for a separate partner. This adaptation is commonly found in various animal and plant species, enhancing reproductive flexibility and efficiency in certain environments.
