### Image Transcription for Educational Purposes

This image is a fill-in-the-blank exercise that focuses on the concept of maternal effect in genetics, particularly in relation to snail shell twisting. Below are the sentences with corresponding options to complete them:

1. **Option:** "dependent on"
   - **Sentence:** The maternal effect refers to the fact that the phenotype of the offspring is _______ the _______ of the mother.

2. **Option:** "deposited in the egg"
   - **Sentence:** Maternal effect genes such as those that control snail shell twisting code for proteins that are ______________.

3. **Option:** "independent of"
   - **Sentence:** With maternal effect genes, the phenotype of the offspring is ________ the genotype of the father.

4. **Option:** "Mendel's law of segregation"
   - **Sentence:** With maternal effect genes, the ratios of progeny that have right or left handed twisting can be predicted since the inheritance of the alleles follows _________________.

5. **Options:** "75% dextral and 25% sinistral," "1:2:1," or "2:1"
   - **Sentence:** In a mating of two Dd snails, the phenotypic ratio will be _______ and the genotypic ratio will be _______.

**Graph/Diagram:**
There are no graphs or diagrams included in this image. The exercise involves selecting text options to complete given statements. The design is interactive, oriented towards understanding phenotypic outcomes based on maternal genetic influence.

This exercise aims to enhance comprehension of genetic inheritance, specifically focusing on how maternal genes can influence offspring traits, a fascinating topic diverging from traditional Mendelian inheritance patterns.
