- 4. Multiple Choice
During meiosis and gamete formation, homologous (paired up) alleles split up
Phenotype
Law of Segregation
Genotype
Dihybrid Cross
- 5. Multiple Choice
During meiosis, the homologous pairs of chromosomes and the matching alleles are lined up independently.
Offspring are a mix of maternal genes and paternal genes.
This increases genetic variation.
Homozygous Dominant
Law of Segregation
Crossing Over
Independent Assortment

- 15. Multiple ChoiceJabba the Hutt has finally decided to settle down and have a family. He has undergone genetic testing and learned that he is heterozygous for Hutt Fungal Syndrome, which is caused by recessive alleles. He is worried that his children might suffer from this syndrome.
