Q
  1. How does inheritance determined by multiple genes differ from
    Mendelian inheritance?
A
  1. Inheritance determined by multiple genes has a larger number of possible genotypes and a larger range of phenotypes possible compared to inheritance determined by a single gene. These traits do not segregate in
    Mendelian patterns.

Q
  1. How does non-nuclear inheritance differ from Mendelian inheritance?
A
  1. Non-nuclear inheritance seen in chloroplasts and mitochondria is maternally inherited. These traits do not segregate in Mendelian patterns.

Q

What’s an example of many genes determining a trait?

A

Hair color because each parental gene has an additive role in determining this phenotype

AABBCC -> dark AaBbCc -> medium aabbcc -> light
