Question

Give Two examples where new species produced through a combination of polyploidy and hybridisation​

Answer 1

Answer:

Triploid and tetraploid

Explanation:

Triploid and tetraploid chromosomes are examples of polyploidy.

Answer 2

$\huge\underline\red{Explanation:-}$

• Triploid and tetraploid chromosomes are examples of polyploidy.

• Polyploids arise when a rare mitotic or meiotic catastrophe, such as nondisjunction, causes the formation of gametes that have a complete set of duplicate chromosomes. Diploid gametes are frequently formed in this way.

• Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. ... With DNA analysis becoming more accessible in the 1990s, hybrid speciation has been shown to be a fairly common phenomenon, particularly in plants.
