Animal
What is the predator's job in an ecosystem?
It's job is to capture and consume another organism for nourishment
What is the definition of Trait?
It is a distinct characteristic of an organism, which may or may not be inheritable.
What is Reproductive Success?
The ability to produce fertile offspring.
What happens during Recombination?
It is the process by which new combinations of alleles that are not found in the parents are produced in offspring.
A change in the DNA sequence of a chromosome is best described as _____.
Fill in the blank.
Mutation
What is the prey's job in an ecosystem?
It's job is to be captured and consumed by another organism for nourishment.
What is the difference between a gene and an allele?
It is a single, more distinct version of a gene.
Why does Natural Selection Occur?
Organisms undergo physical and behavioral modifications to enhance their survival and reproductive success.
What is the definition of a gene pool?
It is all the genes in any populations.
What is the name of the term when alleles or genes being transferred from one population to another?
Gene Flow
What is a desert habitat?
This type of habitat has dryness, limited vegetation, and organisms adapted to conserve water.
What are punnett squares used for?
It is a tool used to analyze the possible allele combinations of the offspring between two individuals.
How is speciation connected to reproductive success?
Because it is when divergence of populations or sub populations of the same species to the point where they can no longer interbreed and generate fertile offspring.
What is a process by which the heritable characteristics of a population change such that the organisms in the population become better able to survive and reproduce in their environment?
Adaptation
These are structures in different species that have similar shapes but different functions, showing common ancestry.
homologous structures
What happens during predation?
It is an interaction between organisms in which one organism captures and consumes another organism
In pea plants, the allele for tall plants T is dominant over the allele for short plants t. If two heterozygous tall plants are crossed, what are the possible Phenothypes of their offspring?
75% Tall
25% Short
What is the difference between Genetic drift and Genetic flow?
Genetic drift is the random change in allele frequencies within a population, while gene flow is the transfer of alleles between populations through migration.
What is the mostly known cause for the founder effect?
Marked population decrease, migration, or isolation.
The variety of different species in an area is called _______.
Fill in the blank.
biodiversity
What is a offspring?
The product of the reproduction of a new organism produced by one or more parents.
In pea plants, the allele for tall plants T is dominant over the allele for short plants t. If two heterozygous tall plants are crossed, what are the possible genotypes of their offspring?
TT - 25%
Tt - 50%
tt - 25%
Give me an example of Survival of the Fittest?
example: Multiple giraffes live in Africa and the ones with shorter necks die because they can not eat from the tall trees. Causing all the next offspring to have longer necks.
Does the Bottleneck effect cause more genetic variation or less. (Explain thoroughly)
The Bottleneck effect causes a reduction in genetic variation. It also causes a reduction of the size of a population to a single or a few individuals. (+200 bonus points if answered 2nd part.)
This is the name of the scientist who proposed the theory of natural selection as a mechanism for evolution.
Charles Darwin
