Heredity
B= brown hair and b= blonde hair
Complete dominance
What is the genotype of someone with the allele pair Bb?
Bb
The preserved remains of evidence of an organism is called what
Fossil
Who came up with the theory of natural selection?
Charles Darwin
Wild foxes are aggressive and unfriendly toward humans. However, Russian scientists have worked since the 1950s to breed a domesticated version of the silver fox. Each year, the scientists choose the tamest foxes to mate together. Gradually, the foxes are becoming more like dogs. They are much more friendly and playful than wild foxes. What technique is used to increase desirable traits in domesticated animals through breeding?
artificial selection
How many daughter cells are produced in mitosis?
2
B= brown hair and b= blonde hair
Complete dominance
What is the phenotype of someone with the allele pair Bb?
Brown hair
What type of fossil are most of the bones of dinosaurs in museums
Mineralized
Where was the theory of natural selection made?
Galapagos Islands
Liam observes a gray wolf and a brown wolf at the zoo. This difference in color is an example of __________________ within a species.
variation
How many chromosomes are in a daughter cell of meiosis?
23
B= brown hair and b= blonde hair
Complete dominance
One parent is homozygous recessive and one is heterozygous. What is the percent chance the offspring would have blonde hair?
50%
Give an example of a trace fossil
footprints, teeth marks, etc
What animal was studied that lead to the discovery of natural selection
finch
In tropical rainforests, birds have evolved to eat the brightly-colored fruits. The fruits have evolved their attractive color so the birds will eat them and spread the fruits’ seeds. What is this an example of?
natural selection
Does mitosis or meiosis go through the PMAT cycle twice?
meiosis
Who was known as the father of genetics and what did he study>
Gregor Mendel, pea plants
How do scientist use layers of soil to determine the age of fossils?
how deep they are buried, what the soil type is
Alex reads about Darwin's research and observations on the Galápagos Island finches. Originally, the finches may have all looked alike. Eventually one adaptation evolved differently in each population based on the type of food they ate. What was this adaptation
beak shape
What is an inherited behavior or physical change that helps an organism survive and reproduce in its environment?
adaptation
Is mitosis or meiosis responsible for growth and repair of cells
mitosis
B= brown hair and b= blonde hair
Complete dominance
If both parents are heterozygous, what is the percent chance the offspring will have brown hair?
75%
What method do scientists use to tell how old bones are?
carbon dating
What are two things that can lead to natural selection taking place?
climate change, new species introduction, etc
Nancy visits a local reservoir where she feeds ducks and other birds. Every time she feeds them, she notices that they fight for the best pieces, and some birds do not get any pieces of food. All living things struggle to get the necessary amount of food, water, and shelter. What is the term for this struggle?
Competition
What phase do the chromosomes line up in the middle?
Metaphase
