Based on inheritance patterns, se_x-linked traits are present on the se_x chromosomes while autosomal traitsare found on the autosomes.
<h3>What is a dominant allele?</h3>
A dominant allele is a copy of a gene which always appears in every generation.
A pedigree is a chart that shows the inheritance of triats in generations of families.
Based on the pedigree given:
- The genotype of the individual #1 is XBXb since the offspring are XBXb and XbY
In the pattern of inheritance, all males receive their X chromosome from their mother.
Se_x-linked pedigrees differ from autosomal pedigrees because the traits are located on the se_x chromosomes.
An autosomal dominant trait require only one allele.
Based on the pedigree, the genotype of the offspring are hH, hH and hH based on the genotype of the parents.
