1 - $300 What is the term for allele separation during gamete formation? Segregation of alleles

1 - $400 Why do we use pedigrees? To determine whether a trait is autosomal or sex-linked; to track a specific trait through a family

2 - $300 How many divisions of meiosis are there? Two: Meiosis I and Meiosis II

2 - $400 What is crossing-over, and when does it happen? Crossing-over occurs in Prophase I and produces new combinations of alleles

4 - $100 Who was the first person to study dihybrid crosses? Mendel

4 - $200 How do pedigrees show that a person expresses the trait we are tracking? The circle or square is shaded

4 - $300 In a pedigree, what do the squares represent? Males

4 - $400 Write an example of a dihybrid cross Punnett square Type answer to appear with a mouse-click here

4 - $500 If a genetic disorder is a recessive X-linked trait, is a male or female child more likely to get the disorder if the father is normal and the mother is a carrier? The male would have a 50% chance of getting the disorder, and the female would be normal

5 - $100 What is a gene? A unit passed from parent to offspring Code for protein Sequence of DNA

5 - $200 What happens during Metaphase I and Metaphase II? Chromosomes line up in the middle of the cell

5 - $300 What are gametes? Sex cells; sperm and egg cells; used for sexual reproduction
