Albinism is primarily associated with mutations in genes located on chromosome 11, specifically the TYR gene, which encodes the enzyme tyrosinase important for melanin production. Other forms of albinism can be linked to mutations on different chromosomes, such as chromosome 15 (OCA2 gene) and chromosome 19 (SLC45A2 gene). These genes collectively influence melanin synthesis and distribution in the body, leading to the condition.
If both parents carry the gene for albinism, which is an autosomal recessive disorder, there is a 25% chance their child will be affected by albinism, a 50% chance the child will be a carrier like the parents, and a 25% chance the child will neither have albinism nor be a carrier. Therefore, there is a 75% chance that their child will not have albinism, either being a carrier or completely unaffected.

Chromosomes(:
It is Homologous chromosomes because they carry thesame genes and homones.
Genes are located on chromosomes and carry hereditary instructions that are passed from parents to offspring. Genes determine various traits and characteristics in living organisms.
The main function of DNA chromosomes is to carry genes.
Yes, you can determine if you carry the albinism gene through genetic testing. If you have a family history of albinism or related conditions, a healthcare provider can recommend specific tests to check for mutations in the genes associated with albinism, such as the TYR, OCA2, or SLC45A2 genes. Additionally, genetic counseling can provide insights into the implications of carrying such genes.
Homologous chromosomes are chromosomes that carry the same sets of genes, with one chromosome inherited from the mother and one from the father. They pair up during meiosis and are crucial for genetic variation and inheritance.
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
Chromosomes in the nucleus of the cell carry the material of heredity, or genes.Hope that helped.
