What else can I help you with?
What is random dating?
I think random dating is when you date random people you do not really know or know much about them.
What are some random experiments to do at home?
some random experiments you can do at home are... floating egg levitating egg breeding bacteria and a lot more
How do you minimize random error?
The only way to minimize random error is to repeat the experiment more times to get a better average. This means your result is accurate but not percise
When are two populations considered new and separate species?
A new species can occur when;1. Change in allele frequencies-genetic drift can result in loss of alleles in a population-one allele becomes the only variation, becomes "fixed"2. Gene flow due to migration-movement of alleles into or out of a population3. Non-random mating-individuals have preferred mates rather than random4. Mutations-a change in DNA can be beneficial, neutral, or harmful5. Natural Selection-best adapted, more likely to survive
What happens when Rare allele is in a small population?
The smaller the population the greater the frequency the allele will increase. When the Old Order Amish came to America in 1744 it was a husband and wife. One of them was a carrier for a recessive genetic mutation. As time went on and inbreeding occured because of the small population more and more children were born with the genetic disorder.
What is linkage disequilibrium?
Linkage disequilibrium is the non-random association of alleles at two or more loci. It is broken down by recombination. Linkage equilibrium = independence between allele frequencies at two different SNPs Linkage disequilibrium = Association between alleles at different SNPs (SNPs are Single Nucleotide Polymorphism - Pronounced snips)
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
What is a heterozygous phenotype?
Having different alleles at one or more corresponding chromosomal loci. Like people who are resistant to sickle-cell anaemia.
What is a heterozygous mixture?
A heterozygous mixture refers to a situation where an individual has two different alleles of a gene at a specific locus. This results in a mixed genetic composition in the individual. This can impact the expression of traits and characteristics by combining the effects of the different alleles.
When two loci are on the same chromosome the phenotypes of the progeny sometimes do not fit the phenotypes predicted?
This discrepancy can be explained by genetic linkage, where the two loci are physically close together on the same chromosome. The closer the loci are, the less likely they are to be separated during crossing over, leading to an unexpected inheritance pattern. This can result in certain combinations of alleles appearing more frequently in the progeny than expected based on Mendelian genetics.
What is the name given to genes that have more than two alleles?
Polymorphic locus or polymorphic gene. Many geneticists use the term locus (plr. loci) for a gene (i.e. section of a chromosome)
What is homozyous?
"Homozygous" refers to an individual having two identical alleles for a particular gene. This can either be two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive). Homozygosity increases the likelihood of genetic traits being expressed.
What factors change the allele frequency of a population?
Factors that can change the allele frequency of a population include natural selection, genetic drift, gene flow, mutations, and non-random mating. Natural selection favors certain alleles, genetic drift causes random changes, gene flow introduces new alleles, mutations create new variation, and non-random mating can lead to specific alleles being passed on more frequently.
Which represents polygenic inheritance of traits?
Breeding of parents and f1 offspring do not follow simple Mendelian patterns. Some simple polygenic traits (two gene loci multiple alleles at one locus) may appear to follow mendelian patterns...such as base coat color in horses. Multiple other dilution alleles at various loci modify the base coat color. More complex interactions between a series of genes become even more complex and sometimes no offspring of 2 parents that have the desired characteristic are produced in the F1 generation.
What is the difference between a factor and an allele?
A locus is a particular location or a marker on a chromosome. It can be a gene but really only needs to be an identifiable location on the chromosome. Alleles differ in that they refer to a particular sequence of DNA at a given locus. The distinction from loci is that multiple alleles can exist for the same locus. http://www.informatics.jax.org/silverbook/glossary.shtml
What does genesis loci mean?
Perhaps you mean genius loci, the guardian deity of a place, or more loosely, a place's characteristic atmosphere
What is it called when the phenotype is determined by more than two unlinked loci?
When the phenotype is determined by more than two unlinked loci, it is referred to as polygenic inheritance. This means that multiple genes at different loci contribute to the expression of a particular trait or phenotype.
