Incomplete Dominance

32.3K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Genetic Variation01:25

Genetic Variation

1.5K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

8.2K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

10.0K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

    Summary

    This study reviews the genetic basis of lens development, detailing key genes and their roles in forming the eye's lens. Genetic mutations can cause lens absence, underdevelopment, or cataracts.

    Area of Science:

    • Developmental Biology
    • Ophthalmology
    • Genetics

    Context:

    • The development of the eye lens is a complex process involving precise genetic regulation.
    • Understanding lens development is crucial for addressing congenital eye disorders.

    Purpose:

    • To review current data on the genetic control of lens development.
    • To identify key genes involved in lens formation, specification, and differentiation.

    Summary:

    • The paper examines genetically regulated pathways in lens anlage formation, specification, and differentiation.
    • It highlights major genes critical for these developmental stages.
    • Disruptions in these genes can result in lens anomalies like anophthalmia, microphthalmia, or various cataracts.
