Cloning of Dolly the Sheep01:08

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual,  the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
In-vitro Mutagenesis01:16

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Area of Science:

  • Animal genetics
  • Reproductive biology
  • Genomics

Background:

  • Livestock populations undergo strong selection for reproductive success, leading to animals with enhanced fecundity.
  • These animals are crucial for identifying genes and regulatory mechanisms controlling reproduction.

Purpose of the Study:

  • To review the identification of mutations affecting ovulation rate in livestock.
  • To explore how these discoveries enhance understanding of ovarian function control.

Main Methods:

  • Review of scientific literature on genetic mutations impacting ovulation rate in sheep.
  • Analysis of identified genes and their role in reproductive traits.

Main Results:

  • Three genes in the transforming growth factor β pathway are linked to ovulation alterations in sheep.
  • Several sheep lines exhibit mutations in single genes with significant effects on ovulation rate.

Conclusions:

  • Genetic mutations play a key role in controlling ovulation rate and reproductive success.
  • Understanding these mutations provides novel insights into the mechanisms governing ovarian function.
