What else can I help you with?
A unit that determines that trait?
A genetic locus is the specific location on a chromosome where a particular gene is located. It serves as a unit that determines the expression of a specific trait due to the presence or absence of alleles at that locus.
What is a polymorphic locus?
A polymorphic locus is a specific position on a chromosome where there are two or more alternative forms of a gene (alleles) present in a population. This variation allows for genetic diversity and can influence traits or susceptibility to certain diseases.
Inbred lines that have same genetic constitution but differ only at one locus are called?
Inbred lines that have the same genetic constitution but differ only at one locus are called "near-isogenic lines" (NILs). These lines are used in genetic studies to isolate the effects of specific genes on traits, allowing researchers to assess the impact of single genetic variations in a controlled genetic background. NILs are valuable in plant and animal breeding as they help in understanding gene function and developing improved varieties.
Location of an allele on a chromosome?
homologous
What is locus heterogeneity?
A term used in those genetic conditions where a single syndrome is caused by different genes in different families, possibly due to the different environmental factors that have influenced them.
A unit that determines that trait?

What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
Are sex linked or autosomal similare?
Not really. Autosomal refers to the fact that a characteristic is controlled at a single genetic locus. Sex linked refers to a gene locus on the sex chromosomes For example. Hemophilia is a sex linked characteristic because the genetic locus for the disease is located on the X sex chromosome. It is also autosomal recessive.
What kind of genetic cross takes into account the behavior of alleles of a single locus?
A monohydrid cross.
What is a polymorphic locus?
A polymorphic locus is a specific position on a chromosome where there are two or more alternative forms of a gene (alleles) present in a population. This variation allows for genetic diversity and can influence traits or susceptibility to certain diseases.
What has the author Rahat Perveen written?
Rahat Perveen has written: 'Genetic and physical mapping around the Treacher Collins syndrome locus'
Location of an allele on a chromosome?
homologous
What is locus heterogeneity?
A term used in those genetic conditions where a single syndrome is caused by different genes in different families, possibly due to the different environmental factors that have influenced them.
What is a monomorphic locus?
A monomorphic locus is a genetic locus where only one variant or allele is present within a population. This means that all individuals within that population carry the same allele at that specific genomic location.
Which is most inclusive A. Allele B. Genotype?
Genotype is more inclusive than allele. Genotype refers to the genetic makeup of an organism, including all alleles present at a particular genetic locus. Allele is a specific form of a gene that can be present at a given locus within an organism's genome.
A locus the location of an allele on a chromosome?
It defines location of a gene on a chromosome. Also, it means a genetic susceptibility factor. It is usually a part of a chromosome when disease is analyzed and broke down. Cancer or heart disease.
Why do allele frequencies always add to one?
Allele frequencies in a population refer to the proportion of each allele for a given gene among all alleles at that locus. Since all possible alleles at a locus contribute to the genetic makeup of that population, the sum of their frequencies must equal one, representing the entire genetic pool for that gene. This ensures that the distribution of alleles reflects the entirety of genetic variation available for that trait within the population.
