Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes.
1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction.
2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions.
3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.

What are three types of genotypes that exist for pea plant height?
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
What are the three conditions for the hardy Weinberg principle?
The Hardy-Weinberg principle states that a population's allele and genotype frequencies will remain constant from generation to generation in the absence of evolutionary influences. The three key conditions for this principle to hold are: 1) a large population size to avoid genetic drift, 2) no mutations, which would introduce new alleles, and 3) no migration, ensuring that there is no gene flow in or out of the population. Additionally, there should be random mating to prevent selection based on specific traits.
What are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

What are the Kinds of variation?
Variations are of following types:- 1.Somatic and Germinal Variations. 2.Continuous and Discontinuous Variations. 3.Determinate and Indeterminate Variations. 4.Meristic and Substantive Variations. 5.Other Variations.
What are the three different combinations of alleles?
If the gene for a trait has two alleles, one dominant (D) and one recessive (d) there are three possible combinations in the genotype: DD (homozygous dominant) Dd (heterozygous) dd (homozygous recessive)
What are three main ways that variations in genotype arise in a population?
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.
What are the possible effects of 'AS' married to 'AS' and why?
There are three outcomes if a person with an AS genotype marries a person with another AS genotype. The offspring has a 50 percent chance of inheriting the AS genotype, and a 25% chance of having a child with an AA or SS genotype. Most couples who share the AS genotype choose not to procreate.
What are three types of genotypes that exist for pea plant height?
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
What are three way from which hypotheses may arise?
Three ways a hypothesis may arise are: 1.) Prior knowledge 2.) Logical inference 3.) Informed, creative imagination
Why are there three different variations of the Congressional Medal of Honor?
The three variations are for the three services. The Navy version is closest to the original. All three use the same distinctive Light Blue ribbon with white stars.
Can you provide some Hardy-Weinberg equilibrium practice problems for me to work on?
Here are a few practice problems to help you understand Hardy-Weinberg equilibrium: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? In a population of 1000 individuals, 64 exhibit the dominant trait for a certain gene. What are the expected frequencies of the three genotypes (homozygous dominant, heterozygous, homozygous recessive) in the population? Try solving these problems using the Hardy-Weinberg equations and principles!
What are 3 break variations?
Three break variations are different sets that form part of a single session
How many of the possible types of offspring had the same genotype as the parents?
Use a punnet square it may be a little tricky though.Just remember which letter is dominant and which one is recessive.heterozygous and Homozygous.

Three Legged Cross's population is 1,500.
What is the population of Three Rings Design?
Three Rings Design's population is 40.
What different problems can be brought by a rapid population growth?
The rise in crime due lack of employment opportunities are some population problems that may arise from rapidly growing cities. Spread of infectious diseases like HIV and AIDS are the other population problems that may arise.
