Terms in this set (63)
What is DNA made out of?
subunits called nucleotides
the capacity of a physical system to do work
Why was the PRIDE GENOTYPE (Alleles) the most important evidence in determining parentage?
It has all the genetic information for the males, females and cubs for four different genes. Using this information you can figure out that the actual parents had to contribute 1 allele each to the cub to prove a genetic possibility
Description of the visible characteristics of an organism
Why do you think the researchers were surprised by the final Genotype Parentage Data?
Researchers found out that not all the cubs belong to the same mother and that lions can move among different prides frequently.
An action commonly observed in individuals throughout a species
Animal hunted or caught for food
Name the three parts of DNA
simple sugar, phosphate group, nitrogen base
How do DNA bases pair up?
they only bond up with their complementary pair
Describe why genetics is now required to study species like these lions.
Many females in a pride raise their cubs communally, so genetic testing is necessary in order to determine who the exact parents are because many of the lions would have similar genetic traits showing high relatedness. Also, prides can relocate to other prides and breed with lions there.
A trait that helps an organism survive and reproduce
the greatest or most complete or best possible.
Level or a position in a food chain pyramid
What were the benefits for Lulu (#630) to raise the cubs there were not hers?
There is an evolutionary advantage to raising the young together because this ensures that Lulu's genetic information will be passed along. Her cub is one of many cubs, so there is a safety in numbers. With more cubs, they have more help hunting.
small sections of chromosomes which are small sections of DNA
Based on your experience with this data from Africa, how is it advantageous for some species like lions to live in a social group?
Protection, group hunting, communal cub raising
Interactions among individuals, normally within the same species, that are usually beneficial to one or more of the individuals
accessible and ready for use
What are chromosomes made of?
tightly coiled DNA
What is the difference between genotype and phenotype?
genotype is something on the inside that you can't see and phenotype is your outer appearance
Why is knowing the parentage important?
Knowing parentage is important in zoo populations and endangered species. Zoologists and scientists are always trying to maximize the gene pools (the amount of genes available in a population) of zoo animals and endangered animals to prevent inbreeding and loss of genetic diversity. Diversity of genes gives more variation and therefore can sometimes help the species survive better. Zoos often work together within a network to achieve this.
The ability to do work
the process of staying alive
What is gene flow? Give an example
the exchange of genes between two populations, so when a certain breed of dogs breeds with another dog breed the genes exchange.
An organism's genetic makeup, or allele combinations.
The amount of energy expended by that organism in a given time period - usually daily
part of an organism consisting of similar cells.
One organism capturing and consuming another organism
the surroundings or conditions in which an animal, or plant lives
Different forms of a gene
What does a pedigree show?
who the parents or relatives are
What is a karyotype?
Photograph of paired chromosomes
An interaction in which individuals of different species compete for the same resources in an ecosystem
the smallest possible amount
How many chromosomes do humans typically have? How many pairs?
46 chromosomes and 23 pairs
An interaction in which individuals of the same species compete for the same resources in an ecosystem
observable actions of living things
How can I tell the gender of a species by looking at their karyotype
females have 2 copies of a large X chromosome and males have one X and one Y chromosome
A group of organisms that can reproduce with one another in nature and produce fertile offspring
keep or lay aside for future use
position where gene is located
Generating energy (ATP) from nutrients
a repeated behavior
producing a desired or intended result
A group of organisms of the same species that live in the same place at the same time
What is an allele?
two forms of the same gene located in the same area of the gene
Information obtained through the senses.
Non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems
to observe or plot the moving path of something
Any living component within an environment in which the action of the organism affects the life of another organism
A group of similar organisms that can breed and produce fertile offspring.
The variability among living organisms from all ecosystems
the difference between the cost of something and what you gained
Non-living things that are found in the ecosystem such as rivers and mountains.
living things, such as plants, animals, fungi, and bacteria
Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent to offspring.
A biological community of interacting living organisms and their nonliving physical environment.
unselfish regard for the welfare of others
Behavior by two or more individuals that leads to mutual benefit
An inherited characteristic that improves an individual's ability to survive and reproduce in a particular environment.
A picture of all the chromosomes in a cell arranged in pairs.
the identity and origins of one's parents
