Answer:
A decay series ends when a stable nuclide is reached - it will no longer spontaneously decay.
Explanation:
In a diploid cell with four chromosomes (two homologous pairs), there are two equally possible ways for the chromosomes inherited from the two parents to be arranged during metaphase I. This variation in the orientation of chromosomes leads to gametes with four equally possible combinations of chromosomes.
Chromosomes
The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
The Greek words for colour (chroma) and body are where the word "chromosome" originates (soma). Because chromosomes are cell structures or entities that are intensely stained by several vivid research dyes, scientists gave them this moniker.
