Synapsis:
•Early
during the first nuclear division.
•Homologous
chromosomes pair along their length.
•Held
tightly by protein ‘zipper’.
<span>Homologous Recombination: </span>
•Genetic
exchange (crossing
over<span>)
occurs between homologous chromosomes. It then becomes a mix of both paternal and maternal genes (father and mother respectively)</span>
Answer:
It shows the three organisms to have evolved from a common ancestor.
Explanation:
An identical sequence of amino acids for cytochrome c in cows, pigs and sheep show that they most likely evolved from a common ancestor. The common ancestor might have evolved over time and in result, three different species were produced. It also shows that they are more closely related to one another than other organisms.
Other properties or traits that are common in these organisms are :
They all are mammals.
They are all livestock animals.
They all are multicellular organisms.
If all nations agreed to reduce global warming then It would be good because the seals need icy conditions. So the less global warming then the more icy habitats there will be and the seals will have more places to live.

<h3>What are plants and animals?</h3>
Plants are large eukaryotic photosynthetic living organisms found on the earth.
Animals are either multicellular eukaryotic organisms which lack the ability to manufacture their own food as plants do, but depend on plants and other animals for their food.
