Hi! I canât say I know what your problem is but I did read that the clumps in the sperm may be nothing harmful and are not necessarily a sign of an underlying disease. They can however, be painful sometimes and their cause might not always be found.
In addition to differences between genes, the arrangement of nucleic acids can differ between copies of the same gene. This results in different forms of individual genes. Different forms of a gene are called alleles. Organisms that reproduce sexually receive one complete copy of their genetic material from each parent.
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits. 1  Since human cells carry two copies of each chromosome they have two versions of each gene. 2  These different versions of a gene are called alleles. 3  Alleles can be either dominant or recessive.
