1
Q
- How does inheritance determined by multiple genes differ from
Mendelian inheritance?
A
- 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.
2
Q
- How does non-nuclear inheritance differ from Mendelian inheritance?
A
- Non-nuclear inheritance seen in chloroplasts and mitochondria is maternally inherited. These traits do not segregate in Mendelian patterns.
3
Q
Can a trait be a product of multiple genes?
A
Yas
4
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
5
Q
Chloroplast and mitochondria contain…
A
their own non-nuclear genome
6
Q
Chloroplast and mitochondria are…
A
randomly assorted to gametes and daughter
cells during cell division
7
Q
- Mitochondria are transmitted from the…
A
egg and not sperm in animals
Such traits are maternally inherited
Mitochondria and chloroplast are transmitted in the ovule and not in the pollen in plants
