Learn about genetic traits by examining some of your own! This article explores the genetic of iris pigment and nearsightedness.

Understand heredity first hand by examining actual examples of dominant and recessive phenotypes that you possess.

Humans are diploid organisms with two sets of homologous chromosomes, but we also contain haploid sex cells with one set and half the number.

What is the relationship between genes, chromosomes and DNA? Genotypes, phenotypes and alleles? Read on to learn how inheritance works.

Once female and male gametes (egg and pollen) have formed, pollination is the process that brings them together so fertilization may occur.

Spores of a moss can endure years of draught, travel hundreds of kilometers and wait silently for the day they germinate and create a new generation of their species.

Mitosis is how the cells of our body make more cells for growth, development and repair. Meiosis is how our body makes sex cells, or gametes (eggs or sperm).

Hemerocallis comes in many flower forms. Learn about unusual form and spider daylilies, two types of beautiful flowers that will add movement to flower gardens.

With primitive bodies that cannot conduct water, bryophytes must be inhabitants of shade and shadow where moisture levels are high.

It's much easier to understand genetics and heredity if you examine actual examples of dominant and recessive phenotypes that you possess.

Meiosis, a type of cell division, results in production of gametes (eggs & sperm). Genetically unique sex cells combine at fertilization to form one-of-a-kind offspring.

It all begins with the fusion of a haploid sperm cell provided by the father and the haploid ovum of the mother. Gametes unite when the nuclei of sperm and egg merge.

When a person has slow metabolism, regardless of how little the amount of food ingested, the result will be an excess of fat, low amounts of energy, and weight gain.

Small and miniature Hemerocallis hybrids by Grace Stamile are excellent for daylily gardens in backyard spaces. These petite flowers add bold colors to containers.

The bacterium Acinetobacter baumannii was often ignored by doctors but now is considered a potentially lethal pathogen in hospitals, due to antibiotic resistant strains.

Explains how one acquires Cystic Fibrosis as well as characteristics of the disease. It also explains that the disease is not contagious and is inherited genetically.

Grow colorful perennial flower gardens with hybrid daylilies. Hemerocallis is a perennial plant for hummingbird and scented gardens.

Rabies is a dreaded disease. Untreated rabies, spread by rabid animals' bites, is a death sentence. Pasteur's vaccine worked to protect against this bullet-shaped virus.

In flowering plants the production of seeds depends on the transfer of pollen and the fusion of male and female gametes.

Ferns and their taxonomic relatives are complex of body but primitive in their mode of reproduction.

Those new to the field of genetics may feel baffled by terminology such as "alleles", "autosomal chromosomes" and "genotype".
