Incomplete Dominance01:43

Incomplete Dominance

19.0K
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.

Animal Mitochondrial Genetics

7.8K
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...

Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

62.5K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Genetic Screens02:46

Genetic Screens

4.6K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Background:

  • Genome sequencing and genomic tools have rapidly advanced the field of equine genomics.
  • The domestic horse genome has been extensively studied, leading to new insights.

Purpose of the Study:

  • To review progress in equine genomics, focusing on reference sequence assembly and analysis.
  • To discuss genomic tools, Mendelian and non-Mendelian traits, performance traits, and genetic testing in horses.

Main Methods:

  • Whole-genome sequencing of a Quarter Horse mare.
  • Utilizing equine single nucleotide polymorphism (SNP) arrays and DNA microarrays.
  • Applying next-generation sequencing (NGS) technologies, including whole-genome DNA sequencing and transcriptome-wide RNA sequencing.

Main Results:

  • Whole-genome sequencing identified variants beyond SNPs, including insertions/deletions and copy number variants.
  • SNP arrays facilitate investigation of simple and complex genetic traits.
  • DNA microarrays enable gene expression analysis across tissues and conditions.

Conclusions:
