Inheritance
What does homozygous mean?
What does heterozygous mean?
Homozygous = genes that are the same
Heterozygous = genes that are different
A type of reproduction that requires only 1 parent, the offspring will be an exact genetic copy
Asexual reproduction
List three ways seeds or pollen can be transported
Wind
Water
Animals
After a male and female spoonbill mate, fertilization
occurs inside the female’s body. The female lays eggs
that will hatch into chicks.
Is this sexual reproduction or asexual reproduction?
Sexual Reproduction
A male frog inflates his throat to make a loud call.
Why might a frog do this action?
to advertise his location to females
What do we call the physical appearance of an organism?
its Phenotype
Male and female jellyfish release sperm and eggs into the water. A fertilized egg develops into a larva that will grow into a polyp. The polyp will release a portion of its body into the water that will grow into an adult jellyfish.
Is this asexual reproduction, sexual reproduction, or both?
Both
List two factors that affect plant growth

how can a bird eating a fruit help with seed dispersal
Seeds could fall to the ground while the bird eats and the seeds could germinate
Or
The seeds could pass through the birds digestive systems and get deposited at another location
Which of the following shows a homozygous dominant genotype?
Aa gg Rr BB vv aa Ww
BB
A type of asexual reproduction where a unicellular organism divides itself into to identical parts, producing offspring
Binary fission
What do seedless plant use instead of seeds to reproduce?
Spores
The ability to produce offspring that are healthy and survive is known as ______________
Reproductive success
A blue eyed recessive parent (bb) is crossed with another blue eyed recessive parent (bb). What chance will the offspring be blue eyed?
Draw a punnett square to answer your question
bb - 100%
Create a punnett square with RR x Rr parents
R is brown eye dominant
r is blue eye recessive
What percentage of offspring will heterozygous?
50%
Identify the following as ADVANTAGES or DISADVANTAGES of sexual reproduction
1. Produces genetic variation
2. time and energy needed to find a mate
3. Species can adapt and evolve
4. diseases are less likely to affect all of population
1. Advantage
2. Disadvantage
3. Advantage
4. Advantage
List the two categories seed plant are put into.
Flowering and Nonflowering
List as many courtship behaviors as you can
Vocalizing
Perform a dance
Display bright colors (feathers or body parts)
Fighting
Building nests or structures
Brings gifts such as food
Points if you named AT LEASE 4
Why do seedless plant usually live in moist/wet environments?
Seedless plant produce spores, spores require water to swim through to reach the egg for fertilization to happen. Without water or a moist environment, fertilization cannot happen.
A cross between BB x bb parents.
B is long hair dominant
b is short hair recessive
Make a punnett square and list all genotypes, phenotypes, and percentages
Bb - long hair - 100%
Identify the following as ADVANTAGES or DISADVANTAGES of asexual reproduction
1. No genetic variation
2. Faster than sexual reproduction
3. Only needs 1 parent
4. Species may be suited for only one habitat
1. Disadvantage
2. Advantage
3. Advantage
4. Disadvantage
What is the male part of a flower and what structures make it up?
What is the female part of a flower and what structures make it up?
Stamen - Anther and Filament
Pistil - Stigma, Style, ovary
List as many parenting behaviors as you can
-build nests or shelters
-Feed their young
-Stay with their young and teach them
- sacrifice their health
-protect their young
Points if you got AT LEAST 4
When a male penguin shelters his chick from the harsh arctic climate, what behavior is the male penguin showing?
