What are homozygous?
Inherited traits that increase an organism’s chance of surviving and reproducing
What are adaptations?

What is the purpose of a punnett square?
To show the possible genotype outcomes
Weaker trait that is designated with lowercase letters
What is recessive?
Aa
What is heterozygous?
Give an example of an animal behavior that increases the probability of successful reproduction by protecting the young
Building a nest
Herding
The name for the male half of the flower
What is the stamen?
Give an advantage of sexual reproduction
Genetic variation
These are the different versions of the same trait. Letters are used to represent those traits
What are alleles
Complete a Punnett Square for two parents with the genotypes BB and Bb. List the percentages for possible offspring genotypes
50% BB
50% Bb
Type of reproduction where 1 parent plant can grow a part of itself. Results in offspring that are 100% identical to the parent.
What is asexual reproduction?
The part of the flower that pollen sticks to
What is the stigma?
How does a squirrel burying acorns aid in plant reproduction?
By helping the seeds to grow into new plants
The genetic makeup of an individual that represented by 2 letters
What is genotype?
Which of the following genotypes will the recessive gene show? Why?
ee Dd FF Gg bb Ll
ee & bb because they are all recessive traits only
Behaviors used by organisms to attract a mate
What are courtship behaviors?
The female half of the flower
What is the pistol?
Give two advantages of asexual reproduction
Quick, no need to find a mate
The physical characteristics of the trait, or what the trait looks like
What is phenotype?
In cats, long hair is dominant to short hair. Complete the punnett square & determine the offspring percentage of short hair & long hair.
One cat is Ll the other is ll
0% LL
50% Ll
50% ll
Why is it important for plants to be able to disperse seeds?
To decrease competition for space & nutrients
The light waves that create a unique pattern on flowers that only pollinators can see
What is UV light?
What are the 4 types of seed dispersal?
