**Title: Determining Genotype and Phenotype in Snail Breeding Experiments**

You are attempting to establish true breeding colonies of snails that are Dextral and Sinistral. You have one female whose genotype you do not know. If you observe Sinistral phenotypes in the F1 offspring, please answer both questions A and B.

**A. Can you determine her genotype (and what is it if so)?**

  - Analysis: If Sinistral phenotypes appear in the F1 generation, this suggests the presence of recessive alleles. This can help determine that the female snail carries alleles for Sinistral orientation. Evaluating the genetic background and pattern of inheritance will guide the determination.

**B. Can you determine her phenotype (and what is it if so)?**

  - Analysis: Since phenotype refers to observable traits, a Sinistral phenotype in offspring does not necessarily indicate the phenotype of the parent. Observing the shell coiling in the parent can assist in determining this female snail's phenotype.

**Note:** Further genetic testing or breeding experiments might be necessary for accurate determination of the genotype and phenotype. Understanding the patterns of inheritance and the principles of genetics is crucial in such experiments.
