Álexa and the members of her immediate family (parents and siblings) have attached earlobe Her maternal grandfather has unattached (free) ear lobes. a. If unattached earlobes are dominant to attached lobes, what is the genotype of he maternal grandfather? b. Alexa's maternal grandmother is no longer living. What could have been the genotype of her maternal grandmother? 7. Joe does not have a bent little finger but his parents do. a. Assuming that one gene completely controls this trait, how is the trait inherited

I am stuck on how to answer question 6a and 6b and 7a
Certainly! Here's the transcription of the image content, ideal for an educational website: --- **Genetic Traits and Inheritance: An Educational Overview** **6. Alexa and Ear Lobe Inheritance:** - Alexa and the members of her immediate family (parents and siblings) have attached earlobes. Her maternal grandfather has unattached (free) earlobes. **a.** If unattached earlobes are dominant to attached lobes, what is the genotype of her maternal grandfather? **b.** Alexa’s maternal grandmother is no longer living. What could have been the genotype of her maternal grandmother? **7. Joe and Bent Finger Inheritance:** - Joe does not have a bent little finger but his parents do. **a.** Assuming that one gene completely controls this trait, how is the trait inherited (dominant, recessive)? Explain how you know. **Page Number: 9** **Mitosis and Meiosis** **b.** Using “B” and “b” to symbolize alleles, what is Joe’s genotype? **c.** Since Joe’s parents have bent little fingers, what are the possible genotypes of Joe’s parents? --- This educational resource discusses genetic inheritance patterns of physical traits such as earlobes and bent fingers, explaining dominant and recessive inheritance.
