Articles related to "Haploid"

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

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

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

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).

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

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.

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.

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.

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

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.

This article series provides information of how mitotic and meiotic cell division differ and how these processes are integral to the human life cycle.

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".

Here are links to free worksheets that can help science educators assess students' understanding of cell division, DNA transcription and translation.

Fungi have a complex life cycle, and mushrooms are no exception. Mushroom reproduction includes both sexual and asexual reproductive stages.

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