Each pair of homologous chromosomes has the same linear order of genes; hence peas are diploid organisms. The same is true for many other plants and for virtually all animals. Diploid organisms utilize meiosis to produce haploid gametes, which contain one copy of each homologous chromosome that unite at fertilization to create a diploid zygote.

They are the form of the genetic material of a cell during cell division. Chromosomes are encoded with genetic instructions for making proteins. These instructions are organized into units called genes. Most genes contain the instructions for a single protein. There may be hundreds or even thousands of genes on a single chromosome.

The pattern of inheritance of Mendelian traits depends on whether the traits are controlled by genes on autosomes or by genes on sex chromosomes.

Two of her three children have the trait (individuals II-3 and II-5) and three of her grandchildren have the trait (individuals III-3, III-4, and III-5). In addition, the trait appears to affect males more than females (in this case, exclusively males are affected), suggesting that the trait may be X-linked. The terms dominant and recessive refer to the way that a trait is expressed, not by how often it shows up in a family.

Despite their differences, they can pair during meiosis through pseudo-autosomal regions, enabling crossover. These regions include genes like SHOX, which affects height and may cause health issues in conditions such as Turner syndrome. Both XY males and XX females have two copies of these genes, while chromosomal aneuploidies can cause anomalies in gene expression.
