Chromosomes

The word you're looking for is "gene." A gene is a unit of heredity that occupies a specific location on a chromosome and is responsible for coding for a particular product, such as a protein or RNA molecule. Genes play a crucial role in determining the traits and functions of an organism.

An individual with an extra copy of chromosome 21 has Down syndrome, a genetic condition that typically results in distinct physical traits such as a flat facial profile, almond-shaped eyes, and a short neck. They may also experience developmental delays, varying degrees of intellectual disability, and have a higher likelihood of certain health issues, such as heart defects. Despite these challenges, individuals with Down syndrome can lead fulfilling lives and often exhibit unique strengths and talents. Early intervention and supportive therapies can greatly enhance their development and quality of life.

Chromatin

People have the same number of chromosome pairs, no matter if they are gay, bi, straight, asexual, or anything else!

The sex chromosomes, X and Y, are not given a number. They determine an individual's sex and are not part of the standard numbered pairs of autosomes.

karyotype. It shows the number, size, and shape of an organism's chromosomes, typically used in genetic testing to identify abnormalities or disorders.

Originally:

no because G2 phase is the cell growth

My Improved answer (copied and pasted from cha cha):

Yes, chromosomes can be seen clearly after the G2 phase. Chromosomes vary widely between different organisms. The DNA molecule may be circular or linear, and can be composed of 10,000 to 1,000,000,000
