If you have an organism in which the A allele is dominant to the a allele, a heterozygote will produce gametes of either A or a. This is what leads to two phenotypes among the offspring in an F2 cross (ie. Aa x Aa). In genetic...
What is a condition where a heterozygous offspring has a phenotype that is distinctly different from, and intermediate to, the parental phenotypes called? What are alleles and how do they relate to genetics? What is a gene? What is an allele? Give an example of 2 alleles of a ...

What is an Allele? Sometimes, there are different forms of genes from the same person. These are calledAlleles(say a-leel). To make this easier, let us use specific examples. Let us say you have blue eyes. It would be very likely that your mum or dad also had blue eyes. If even ...
each unique DNA molecule in the library is bound to the surface of a bead or a flow-cell and PCR amplified to create a set of identical clones. In the case of Ion Torrent technology, a process called “tem...
This second generation is called "F2." He determined that the white-flowered trait was recessive. It was able to skip a generation because the heterozygous plants of F1 carried the recessive allele without expressing the trait. Traits that are inherited this way are examples of simple ...
During prophase I of meiosis I, homologous chromosomes (i.e., the two copies of each chromosome inherited from each parent) pair with each other and recombine by crossing over, leading to new combinations of alleles. Meiosis produces haploid cells with new allele combinations different from those...
The Punnett square illustratesMendelian genetics. A person with two alleles for brown eyes is homozygous dominant. Someone with two alleles for blue eyes has a homozygous recessive allelic pair. Heterozygous individuals have one allele for brown and one allele for blue eyes, for instance. ...
These chromosomes are made up of hundreds of individual alleles, which are inherited from parents and are expressed as either dominant or recessive traits. Each allele or gene is responsible for a specific single part of the phenotype in these simplified terms. ...
One is purely green dominant, expressed as “GG,” each “G” representing an allele; the other is completely blue recessive, “gg,” which means this parent is actually blue in color. Since any offspring they have gets one allele from each parent, all of their offspring would have colorat...
