Kelainan yang di sebabkan gen resesif autosomal

Hi Hi assalamualaikum warahmatullahi wabarakatuh meet me again with me Widyaningsih this time we are still discussing the chapter of human heredity on the material of hereditary disorders caused by autosomal recessive alleles Okay, listen carefully, what we will discuss is disorders caused by autosomal recessive alleles, the first disease we will discuss is albino, albino

is a disease of the absence of melanin pigment in the skin, hair and eyes, the genotype is a large, a large, normal, homozygous, a large, a small, normal, heterozygous, and small-small albino, for example, there is a marriage between a normal heterozygous marrying a normal heterozygous, it will produce a normal home, so that 25%, 50% normal, heterozygous, and 25%

albino, the next recessive disease is mental disorders or phenylketonuria or pekku, TKU is a disease of the body's inability to form the enzyme phenyl alanine so that urine contains phenylketonuria or PKU Well, you can see from the picture, the difference between normal and phenylketonuria causes mental disorders, including stupidity, debility imbicile and idiot

very slow reflex reactions are generally short-lived genotypes enlargement-enlargement normal homozygous p large p small normal heterozygous and P small-small pecco the next disease we will discuss is cyclemia well it is a disorder of red blood cells or erythrocytes in the shape of a crescent so that the binding capacity to oxygen is very low impaired spleen function and

causes death Well you can see the shape of the erythrocytes cyclemia large ice large ice normal homozygous large ice small normal heterozygous and Escape small Silet cyclemia the next disease which is autosomal recessive is xeroderma pigmentosum xeroderma pigmentosum is a pigmentation disorder that causes the skin to be very sensitive to sunlight xeroderma
