Which is the definition of heredity?
organism adaptation to its environment
changing traits of organisms
the passing on of genetic instructions from one generation to the next generation
how traits are determined by genes
The mom cat shown had kittens with an orange male cat. Which best explains how two kittens are gray and one is orange?
the kittens got all of their genetic material from their gray mother
the kittens got all of their genetic material from their orange father
the kittens did not get genetic material from either of the parents
the kittens got half of their genetic material from their gray mother and half of their genetic material from their orange father
What is the best explanation for why the arctic fox shown has white fur?
the snow covers his fur, making it turn white from the water
the fox chose to have white fur because it looks nicer in the arctic environment
the gene for white fur was passed down from the fox's parents through heredity
the sun turned the fox's fur white
What is true about asexual reproduction?
it results in diverse offspring
it results in uniform offspring
it requires two parents
it can lead to better survival if the environment changes
which type of reproduction would result in the greatest diversity/variation of offspring?
budding
sexual reproduction
binary fission
asexual reproduction
There are many different breeds of dogs and each breed has unique traits. What is true about the different breeds of dogs shown here?
the traits of the different dog breeds are caused by asexual reproduction and all of the dogs are genetically identical
the traits of the different dog breeds are caused by sexual reproduction and all of the dogs are genetically identical
the traits of the different dog breeds are caused by asexual reproduction and all of the dogs are genetically diverse
the traits of the different dog breeds are caused by sexual reproduction and all of the dogs are genetically diverse
Which is NOT true of sexual reproduction?
requires two parents
offspring are uniform
requires more time/energy to reproduce
results in greater genetic variation
which of the following is a difference between asexual and sexual reproduction?
offspring from asexual reproduction are produced more slowly
offspring from asexual reproduction are more uniform
offspring from asexual reproduction are larger
offspring produced by asexual reproduction require more energy
Which cell organelle governs your inherited traits?
the cell membrane because it determines what enters and leaves the cell
the nucleus because it holds the genetic material (DNA)
the mitochondria because it converts energy for the cell
the chloroplast because it makes food for plant cells
which cell parts are involved in the passing on of genetic information from parents to offspring?
nucleus, chromosomes, and genes
cell membrane, nucleus, and cell wall
genes, cytoplasm, and cell membrane
chromosomes, cytoplasm, and vacuoles
