Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>

Answer:
curdling of milk is a chemical change.
Explanation:
because it formed by a chemical process of fermentation. moreover, a chemical change is a change that can't be reversed. This process can't be reversed as well so it's a chemical change
