A genetic factor that blocks another genetic factor
dominant trait
How many parents are involved in asexual reproduction?
one
give an example of a courtship behavior
dancing, singing, bringing gifts, fighting other males
phototropism is the growth of a plant towards or away from _________
light
When the two alleles of a gene are the same, the organism is said to be ________.
homozygous
True or false: sexual reproduction results in offspring that are identical to the parent
false
True or false: some traits are influenced by both genetic and environmental factors
true
pollination
Draw a Punnet Square of Bb x Bb
BB, Bb, Bb, bb
an example of an organism that is capable of regeneration
sea star, flat worms, some plants
why is protecting young important?
increases the probability that offspring will survive and continue to help pass genes as offspring have their own kids as well!
Thigmotropism is the response of a plant to ___________
A section on a chromosome that has genetic information for one trait
gene
A form of asexual reproduction in which offspring grow from a part of a parent plant
vegetative reproduction
What's the difference between an innate behavior and a learned behavior?
innate: a behavior that is inherited
learned: a behavior that develops through experience or practice
Give an example of a flowerless seed plant
pine tree
genotype: the actual alleles, the genetic component
phenotype: how a trait appears or is expressed
List an advantage and disadvantage for BOTH asexual and sexual reproduction.
asexual
advantage: less time, don't have to find a mate, pass all your genes
disadvantage: no genetic diversity- will pass all mutations and harder to adapt
sexual
advantage: genetic diversity
disadvantage: only get to pass 1/2 genes
give an example of a trait that is determined by mostly genetic factors and a trait that is determined by mostly environmental factors
genetic: type of fur a dog has, eye color, hair color
environmental: obedience of a dog, language, culture (preferences, likes)
the female reproductive part on a flower is called ________
the pistil
