What can happen to a population of organism with limited variation in the genotype if environmental condition changes?

It will die off if the environmental condition changes drastically. This is because if the gene pool is large, i.e. lots of variation in the genotype, natural selection causes some to die off but others can still survive if they have characteristics adapted to the new conditions. But if the genotype is limited, they sadly don't have "other forms" of genes, so if the new condition is bad for them, the population is equally affected and they die.

What is phenocopy?
A phenocopy is a variation caused in the phenotype due to environmental conditions. It will resemble the normal expression of the genotype, and not it's own.
Why is height continuous variation?
You have the gene of tallness, but you don't eat enough so that your body size doesn't change. Continuous variation in human population is always the result of interaction between genotype and the environment
The phenotype of an organism can be influenced by?
Genetic and environmental effects
What is the combination of actual genetic makeup and the environmental effect on that makeup?
its is the organism's genotype

What is true of a woman with the genotype?
She is a carrier of hemophilia but does not have the condition
What is the visible product of gene and the environments influences?
The old saying is that Phenotype = Genotype + Environmental Factors.
The idea that organisms with a particular genotype will have better reproductive success than organisms with a different genotype is called?
Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
What is the genotype of people who have the genetic condition sickle cell disease?
BB
What is the name of the condition when a person has inherited the genotype HH?
Homozygous dominant.
What does the Hardy Weinberg principle predict?
Genotype frequencies in a population.
What is homozygous recessive genotype?
variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the genetic material for natural selection. Genetic variation is brought about by mutation, which is a permanent change in the chemical structure of a gene. Polyploidy is an example of chromosomal mutation. Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more).
