Answer 2

Euploids

Question 3

Doubling of the same chromosome set
Genomes identical with each other

Answer 3

Autopolyploid

Question 4

-Is the product of interspecific hybridization
-Arises via hybridization between 2 species
-A polyploid organism which originates by c-ombining complete

Answer 4

Unit of polyploids that contain either an addition or subtraction of 1 or additional specific chromosome(s) to the entire range of chromosomes.

Answer 5

Aneuploids

Question 6

Refers to the enlargement of plant cells due to their increased amount of DNA, causing plant organs to enlarge as well. This enlargement has been associated with fitness advantages in polyploids, enabling them to successfully establish and persist.
