The transmission of characteristics from parents to offsprings.
|
|
|
Difference between characteristic and trait.
|
Characteristic - Category (Ex: Height) - a gene
Trait - Options (tall or short) - the alleles (T or t) |
|
|
Pollination
|
When pollen from from male flow is transferred to a female flower.
|
|
|
Anthers

Alleles
|
|
|
Law of segregation
|
Pairs of alleles separate- Happens in anaphase 2.
|
|
|
Dominate
|
Masked, or dominated, the other factor for a specific characteristics
|
|
|
Recessive
|
Trait that did not appear.
|
|
|
Law of Independent Assortment
|
Alleles for different characteristics align on their own if found on separate chromosomes. Otherwise, they line up together. Happens during metaphase I.
