WebBy analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, … WebFirst of all, determine whether the condition is recessive or dominant. If the trait is dominant, the trait must be one of the parents'. If the phenotype is recessive, because they may be heterozygous, no parent is expected to have the phenotype. Then, determine whether an autosomal or sex-linked (usually X-linked) trait appears on the chart.

Genotype vs Phenotype: Examples and Definitions

WebAug 21, 2024 · Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked. This is known as complete genetic dominance. WebGenotype of Parent 1 (blue eyes) and Parent 2 (brown eyes). As you can see there is a 50% chance that the homozygous recessive trait of blue eyes will be shown on their next kid, a 50% chance that the heterozygous dominant trait of brown eyes is given on the next offspring, and a 0% chance of a homozygous dominant trait given to the offspring. small mains powered vacuum cleaners
