Sexual or Asexual
This type of reproduction makes a clone of the parent organism
Asexual Reproduction
Horses and cows live in the same fenced pasture. The grass is the only source of food available to the horses and cows.
Which animals would compete?
All animals compete
The eye color of children often resembles the eye color of their parents. Which of the following is genetically passed from parents to children?
a. Particles of color are passed from parents to children.
b. Cells that become the colored part of the eye are passed from parents to children.
c. Genes on DNA that contain the information that determines eye color are passed from parents to children.
d. Nothing having anything to do with eye color is passed from parents to children.
c. Genes on DNA that contain the information that determines eye color are passed from parents to children.
Structural changes to genes located on chromosomes that may affect proteins are called:
a. adaptations
b. reproductive strategies
c. alleles
d. mutations
d. mutations
DOUBLE POINTS! In humans, dimples (D) is dominant over no dimples (d). A man who has no dimples marries a woman who is heterozygous for dimples.
If the man and woman had a child, what is the probability that the child would have dimples? (Draw the Punnett Square to support your answer.)
50%
In sexually reproducing organisms, such as cats, how much genetic information is passed from parent to child?
50%
Which of the following statements about competition between animals is TRUE?
a. Animals compete for food when it is limited, but they do not compete for water when it is limited.
b. Animals compete for food and water when they are limited, but they do not compete for shelter when it is limited.
c. Animals compete for food, water, and shelter when they are limited.
d. Animals do not compete for any resources, even when they are limited.
c. Animals compete for food, water, and shelter when they are limited.

What affect do mutations have on organisms?
a. All mutations are harmful to organisms because they disrupt protein function or gene regulation.
b. All mutations are beneficial to organisms, because they improve protein function or gene regulation.
c. All mutations have no effect on organisms, because they do not significantly affect protein function or gene regulation.
d. Some mutations are harmful, some mutations are beneficial, and some have no effect on the organism.
d. Some mutations are harmful, some mutations are beneficial, and some have no effect on the organism.

b. budding in yeast
c. regeneration of a lizards tail
d. pollen fertilization in a flower
d. pollen fertilization in a flower
Do plants compete, animals compete, or both compete?
Both compete
In humans, being able to roll your tongue (R) is dominant over not being able to roll your tongue (r). A man who cannot roll his tongue marries a woman who is heterozygous for tongue rolling.
State the following pheno- and genotypes.
Father's phenotype:
Father's genotype:
Father's phenotype: Cannot roll his tongue
Father's genotype: rr
Genetic mutations can result in changes to proteins, which can affect the _____________________ of an organism.
a. structure and function
b. structure but not the function
c. function but not the structure
d. physical attributes
a. structure and function
What is the difference between heterozygous and homozygous
heterozygous has different alleles (Aa) and homozygous is the same allele (AA or aa)
What is an advantage of asexual reproduction?
a. it is quick and requires little energy to find a mate and reproduce
b. it is uncertain
c. it guarantees favorable genes are passed to the offspring
d. It allows animals to reproduce without needing mates and plants to reproduce without needing pollinators.
d. It allows animals to reproduce without needing mates and plants to reproduce without needing pollinators.
Removing broken eggshells from the nest increases the chances that:
a. the gull’s offspring will survive
b. the gull’s chicks will get food
c. the gull will be away from its offspring at a given time
d. the nest will stay clean so the gull can sit on the eggs
a. the gull’s offspring will survive
How does the wind blowing seeds for plants like dandelions and pine trees help increase their chance of survival?
a.It prevents insects from eating the seeds
b.It allows the seeds to travel to new, diverse environments
c.It makes the seeds heavier and more resilient.
d.It reduces competition with other plants.
b.It allows the seeds to travel to new, diverse environments
Electromagnetic radiation ___________ gene mutations.
a. often causes
b. rarely causes
c. never causes
d. has no direct effect on
b. rarely causes
Consider two alleles of flower color: purple and white. Purple is a dominant trait and the BB and Bb code for purple. If two alleles produce bb, a white flower will occur which is the flower’s what?.

What is the most likely purpose of thorns on roses?
to protect from predators or to survive
A student suggests that guarding the nest increases the chances that the female’s eggs will hatch. Which of the following observations best supports this claim?
a. Fewer eggs are eaten when females keep egg-eating snakes away from the eggs in their nests.
b. Some females stay at their nest with their eggs for several days after laying them.
c. Many egg-eating snakes attack and try to eat the eggs in female skinks’ nests.
d. Egg-eating snakes move away from the eggs when the females stay at their nest.
a. Fewer eggs are eaten when females keep egg-eating snakes away from the eggs in their nests.
The graph below shows the daily weight gain of three different fish species based on pond depth. What can you conclude from this graph about 0.8 deep ponds compared to 1.2 deep ponds?
