What happens to a population when genetic variation decreases?
When genetic variation decreases in a population, it becomes less adaptable to changes in the environment. This can lead to reduced fitness and an increased risk of extinction. Inbreeding and higher susceptibility to diseases are also common consequences of decreased genetic variation.
Differentiate direct proportion from inverse proportion?
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Why small numbers of surviving tigers a cause of worry from the point of view of genetics?
The small number of surviving tigers is a cause of worry because of inbreeding. Inbreeding decreases the possibility of viable offspring.
What is direct and indirect proportion?
Direct Proportion-As one of the value increases,so does the other. Indirect Proportion-As one value increases,the other decreases. ~Hannah^^
What happens as the population decreases?
As a population decreases the death rate is higher or equal to the birthrate.
What is the effect of a limiting on a population?
The population decreases.
What are the 3 different kinds of proportion?
*direct proportion - As one values increases, so does the other. *indirect proportion - As one values increases, the other decreases. *partitive proportion - involves identifying parts of a whole based on a given ratio of these parts.
What is inverse proportion?
Inverse proportion is when one value increases, as the other decreases. For example the number of builders building a wall and the number of days it takes to build a wall are 2 quantities in inverse proportion because the more builders there are, the less time it takes to build the wall (there are more people working on it, so it will be built quickly). As the number of builders increases, the number of days to build the wall decreases. This is inverse proportion.
Kinds of proportion?
1. Direct Proportion As one value increases, so does the other. 2. Indirect Proportion As one value increases, the other decreases. 3. Partitive Proportion A proportion describing the total amount being distributed into two or more unequal parts. Miwa D. Oguro
True or false if a prey population decreases the population of its predator probably will decrease as well-?
It is true to say that; If a prey population decreases, the population of its predator probably will decrease as well.
What is the effect of a limiting factor on a population?
The population decreases.
What is population inversion?
Inverse population density is when the population density decreases, the population growth rate also decreases. This is opposite to density dependent because here the population growth rate decreaes as population density increases.
