Polygenic inheritance.
The phenotype for YySs would depend on the specific traits controlled by the Y and S genes. Without knowing the specific traits and their dominance or recessiveness, it is not possible to determine the exact phenotype. Each allele (Y and S) will contribute to the overall phenotype in conjunction with any other alleles present at the respective loci.
In Mendelian inheritance the allele has a one to one effect on the phenotype. A polygenic effect is given when many genes contribute in an additive fashion to the phenotype. Height is such and may have as many as eight genes contributing to the effect. Behavior is also of this type. Eye color is more Mendelian in nature.
To determine the recombination frequency between two genetic loci, one can analyze the frequency of crossover events that occur during meiosis. By studying the inheritance patterns of alleles located at the two loci in a population, researchers can calculate the recombination frequency as the percentage of offspring that show a recombination of alleles. This frequency is a measure of the distance between the two loci on a chromosome.
Homologous chromosomes carry genes for the same traits at corresponding loci. They are similar in size and shape and are inherited from each parent.
The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait. For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink coloured petals). This is because P is dominant to p, and will always be expressed. Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.
The phenotype for YySs would depend on the specific traits controlled by the Y and S genes. Without knowing the specific traits and their dominance or recessiveness, it is not possible to determine the exact phenotype. Each allele (Y and S) will contribute to the overall phenotype in conjunction with any other alleles present at the respective loci.
Having different alleles at one or more corresponding chromosomal loci. Like people who are resistant to sickle-cell anaemia.
The position is called locus (plural: loci).
There are infinitely many loci. So the answer depends on which 4 locis you mean.Incidentally, it should not be "loci's" which means belong to the loci.
It is called a locus (plural = loci).
Chromosomal Loci is a Heterozygous
Loci Communes was created in 1543.
chromosome. where they are located is called the locus. plural= loci
C) alleles, known as their loci
Loci system
HLA typing either by serologic (blood fluid) or DNA methods is reported as the phenotype for each HLA loci tested. The antibody screen test is reported as the percentage of panel reactive antibodies (PRA).
Genius Loci - Bernice Summerfield - was created in 2006.
