No. Sexual reproduction process does not depend upon the number of chromosomes in an organism. Chromosome numbers usually are expressed in sets. 2 sets of chromosomes are present in body cells of organisms. For example, human bears 23 pairs which means 46 numbers of chromosomes. The cells with 2 sets of chromosomes are called diploid cells (2n) and haploid cells contain only one set (n) of chromosomes. Gamete cells are always haploid which are obtained by meiosis cell division of diploid cells. In sexual reproduction fusion of two haploid gametes (male and female) results in formation of zygote which id diploid.So, the number of chromosomes present ina cell whether it is small (cat - 38 chromosomes) or large (butterfly- 380 chromosomes) does not affect sexual reproduction.

Which term is defined as all the genes in a person's twenty-three pairs of chromosomes?
Humans without a disorder will have 23 pairs of chromosomes. However, there are many disorders caused by different numbers of chromosomes. For example, Trisomy 21 (Down Syndrome) is a disorder caused by the presence of an extra chromosome 21.
What clues to the presence of certain genetic disorders can be seen in a karyotypes?
-Extra, missing or damaged chromosomes could show the presence of genetic disorders.
Is a pair of corresponding chromosomes is homozygous true or false?
The corresponding pair of chromosomes may homozygous as well as heterozygous, depending on the presence of dominant and recessive genes.
What are the sex chromosomes of male human being?
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
The presence of a spore in a vegetative bacterial cell helps establish that the organism is of which genus?
Bacillus and Clostridium

An organism that will die in the presence of oxygen is called a?
anaerobe
What does the root poly- mean in the words polypolidity and polypeptide?
The root "poly-" means many or multiple. In polyploidy, it refers to the presence of multiple sets of chromosomes in an organism. In polypeptide, it signifies a chain of multiple amino acids linked together.
Which was the earliest multicellular organism that developed in the presence of oxygen?
prokaryotic
The presence of which organells would identify an organism as an autotroph?
nuclei
Could you swab the portal of entry to detect the presence of the organism?
no
What is a baby's gender if he or she has XXY sex chromosomes?
Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.
What clues to the presence of certain genetic disorders can be seen in a karyotypes?
-Extra, missing or damaged chromosomes could show the presence of genetic disorders.
What common condition is caused by the presence of three copies is chromosomes 21?
Down syndrome
Is a pair of corresponding chromosomes is homozygous true or false?
The corresponding pair of chromosomes may homozygous as well as heterozygous, depending on the presence of dominant and recessive genes.
The presence of which structure provides evidence that an organism is capable of locomotion?
flagellum
Organism such as yeast which depends on the presence of free oxygen to survive?
Aerobe
