Describe or explain how SNPs in genes at evolutionary conser

Describe or explain how SNPs in genes at evolutionary conserved breakpoints can lead to dramatic phenotypic differences between species like chimpanzees and humans even though their genomes are 98% similar? Provide and describe or explain an example of one gene with SNP differences between gorillas and humans that might have resulted changes between humans and apes.

Solution

i can provide u hints

snp means a single nucleotide change in genomic sequence ..... and thus sequence forms different forms .... hence it is called single nucleotide polymorphism .... they can be helpful or disadvantages ... if mutation is advantageous it is called adaptive SNP if it is harmful it is say a pathogenic SNP .... NOW AS U SAY ... if the region of genome is conserved it means that region does not fall in junk DNA part and can code for some important protien ... and if SNP occurs in its sequence it can change the amino acid at protien level hence make protien non functinal ... say a snp occuring at active site of protien .....

okay one gene with differences in snp would be gene for melanin the snps in promoter sequences of melanin would have led apes producing more mealanin in skin than humans

Hope it helps
