We refer to two genes as alleles of each other when they are inherited as alternatives to each other. In molecular terms, alleles are different forms of the same gene. There can be more than two alleles of a gene in a population of organisms. But any given organism has only two alleles...
How are haplotypes inherited by children from their parents? Single Nucleotide Polymorphisms: Single Nucleotide polymorphisms (SNP) are a type of genetic marker that arise due to the point mutation introducing alternative nucleotide bases at the location. These are often inherited across generations. Ans...

How would a punnet square be completed when the parents are BB and bb, and with the Alleles/Genes both being B? How are genetics and cancer related? Explain fully why and where genetic links are found with respect to cancer. How can genetic markers be passed f...
If a pea plant receives a tall allele from one parent and a short allele from the other parent the offspring pea plant is heterozygous. Alternatively, if a pea plant receives two tall alleles or two short alleles the offspring pea plant is homozygous because the two alleles are the same....
Alleles are alternative versions of the same gene. Image by: vitstudio, Shutterstock Marker A sequence of DNA that has a determined location on the chromosome. They are landmarks used to track inheritance. Autosomal-Recessive This term refers to inherited conditions. Recessive conditions are those...
These genes are encoded pieces of information that comes from both parents, these genes are found on any of the 23 pairs chromosomes; these chromosomes that contain genes form the human genome. 22 chromosomes all contain the same genes although slight variations of alleles, alleles are alternate ...
Genotype refers to the genetic makeup of an organism. There are several types of genotypes that determine characteristics and traits. Here are the three types of genotypes you should know about: Homozygous dominant – An organism has two dominant alleles for a gene. ...
According to the Utah State Office of Education, a Punnett square can be used to predict the probability that a particular genotype will occur in offspring by taking the alleles of the two parents and combining them. The genotype will influence the phenotype, depending on whether the alleles are...
When a person inherits one (t) from the father and then one (t) from the mother, the recessive alleles (tt) are inherited and the person can not roll their tongue. As can be seen in thePunnett squareabove, this would happen approximately twenty-five percent of the time. (Note that th...
