What does the Hardy Weinberg principle predict?
Genotype frequencies in a population.
What idea did Hardly and Weinberg disprove?
Dominant alleles become more common in each generation
What did Hardy and Weinberg discover about the frequencies of alleles from one generation to the next?
That they change frequency from one generation to the next and can be easily calculated, with morphological traits visible and Mendelian expression seen, by this polynomial expansion.p2 + 2pq + q2 = 1-----------------------
What does being in Hardy-Weinberg equilibrium mean for a population?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. When mating is random in a large population with no disruptive circumstances, the law predicts that both genotype and allele frequencies will remain constant because they are in equilibrium.
What do the letters inside the punnent square stand for?
The letters on the outside are the genotypes of two parents. Inside are the possible genotypes of possible offspring of the two
What does the Hardy Weinberg principle predict?
Genotype frequencies in a population.
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
The condition in which genotypes have identical alleles?
homologous
What idea did Hardly and Weinberg disprove?
Dominant alleles become more common in each generation
What genotypes is heterozygous?
A heterozygous genotype, is the genetic makeup of different alleles.
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
What are multiple-allele traits?
Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).
What information does a Punnett square provide?
Possible alleles in the gametes of the parents
What did Hardy and Weinberg discover about the frequencies of alleles from one generation to the next?
That they change frequency from one generation to the next and can be easily calculated, with morphological traits visible and Mendelian expression seen, by this polynomial expansion.p2 + 2pq + q2 = 1-----------------------
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
What are the 5 hardy weinberg principals?
The five Hardy-Weinberg principles for non-evolving populations are extremely large population size, no gene flow, no mutations, random mating, and no natural selection. An extremely large population size is necessary because the smaller the population, the greater the role chance fluctuations play in allele frequencies from generation to generation. It is important that there is no gene flow because that transfer of alleles between populations can alter allele frequencies. Similarly, mutations modify the gene pool by introducing/removing genes from chromosomes or by changing one allele into another. Random mating is important so that individuals do not preferentially choose certain genotypes in their mates. Also, there must be no natural selection because if individuals carrying different genotypes had different survival and reproductive success, then that would alter the allele frequencies.
