How many sex chromosomes are in a human gamete?Sex chromosomesHuman chromosomes typically exist in somatic cells as pairs. Normal somatic cells are diploid and contain a total of 23 pairs of chromosomes: 22 of these pairs are autosomes and one is a pair of sex chromosomes. Gametes are ...

3) Humans have somatic cells, which are any cell other than a gamete, have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes from a cell. The 2 chromosomes in each pair are called homologous chromosomes or homologs. The sex chromosomes are X and Y....
Sperm is the male gamete that is specialized to transmit the paternal genome to the next generation through sexual reproduction. To smoothly accomplish this task, a sperm nucleus has a highly compact shape in most animals. The bulk of chromosomal DNA in mature sperm interacts with arginine-rich ...
Viable zygotes are formed only if a gamete containing nine chromosomes is fertilized by another with eight chromosomes. Thus, an egg with nine chromosomes fertilized by a sperm with eight would give rise to a female, and an egg with nine chromosomes would result in a male. Combinations of ...
They found non- disjunction of B's at the second pollen-grain division and preferential fertilisation of the egg by the gamete carrying the B's. These mechan- isms together tend to ensure the retention and possible increase of B chromosomes in the population. This investigation was undertaken ...
