Euploidy isa)One chromosome more than haploid setb)One chromosome more...
Euploidy refers to the change in the complete set of chromosomes, i.e. loss or gain of the full set of chromosomes (Exact multiple of haploid set of chromosomes). The term euploidy designates genomes containing whole sets of chromosomes. So, the correct answer is option 'D'.
Euploidy isa)One chromosome more than haploid setb)One chromosome more...
Explanation:
Euploidy refers to a condition in which a cell or organism has an exact multiple of the haploid set of chromosomes. This means that the total number of chromosomes in the cell or organism is a perfect multiple of the haploid number.
Here is a breakdown of the options provided in the question:
a) One chromosome more than haploid set:
- This option does not describe euploidy as it indicates an additional chromosome beyond the haploid set, which would result in an aneuploid condition.
b) One chromosome more than diploid set:
- Similar to option (a), this option also describes aneuploidy rather than euploidy.
c) One chromosome less than haploid set:
- This option suggests a chromosomal deficiency compared to the haploid set, which is again indicative of aneuploidy.
d) Exact multiple of haploid set of chromosomes:
- This option accurately describes euploidy, where the total number of chromosomes is a precise multiple of the haploid number. This condition maintains the balance of genetic material and is considered normal in certain organisms.
Therefore, the correct answer is option d) Exact multiple of haploid set of chromosomes, as euploidy specifically refers to having a complete multiple of the haploid chromosome number.
