This picture of the chromosomes from one cell of an organism is called a...
karyptype
gene map
genotype
allelic frequency
Why are there two copies of every chromosome in this picture?
Organisms receive one chromosome from the mother, one from the father.
So that there is a back-up copy in case one gets damaged.
There are too many genes to fit on one chromosome.
One copy gives organisms traits, the other gets passed on to their offspring.
What do we call sections of DNA that are the code for producing traits of organisms?
Gene
Chromosome
Nucleus
Genome
Which of the following ways for a lion to hunt is the most energy efficient?
Hunting smaller prey less often
Hunting smaller prey more often
Hunting larger prey less often
Hunting larger prey more often
What is net energy gain?
Energy gained by eating the prey
Energy gained by eating the prey minus the energy lost by hunting the prey
Energy gained by eating the prey plus energy lost by hunting the prey
Number of prey hunted multiplied by the energy available from the prey
Which of the following is true about how many of each prey a lion hunts per day?
The more energy available from the prey the more of that prey they must hunt.
The less energy cost to hunt the prey the less of that prey they must hunt.
The more net energy the prey provides the more of that prey they must hunt.
The energy cost to hunt the prey must be less than the energy the lion has stored.
Does the genetic data support the geographic data for the lion prides?
Yes, in general, prides that live closer geographically are more genetically similar.
No, most of the prides that live close geographically are genetically different.
How can this DNA evidence be used when comparing lion prides?
It can be used to determine relatedness among prides to see which prides are the most genetically similar.
It can be used to determine whether individuals are members of the same species.
It can be used to determine if a species is extinct.
It can be used to determine the number of lions in a pride.
Which of the following best explains why Lulu benefited from raising cubs that were not her own?
Lulu was a very generous and loving lion that just wanted to care for everyone in her pride.
Lulu was most likely related to the other females in the pride and taking care of their cubs would increase the chances that the cubs survived and passed genes from their family on to a new generation of cubs.
Lulu was the dominant female and she had to take the cubs, even if it meant she would be risking her life.
Lulu had a mate in another pride that she wanted to raise the cubs with.
Should scientists use only 1 gene when determining relatedness among individuals or prides?
Yes
No
