Question

Does phenotype ALWAYS change with genotype?

Answer 1

Wat kind of genotype an organism has decides the phenotype. But sometimes small change in genotype does not affect the phenotype because in complex organisms more than 1 gene codes for a particular phenotype.

Answer 2

No, because let's say we have a genotype of HH and Hh, where H is the dominant allele, and let's say it represents black hair colour. and h is the recessive which represents brown hair colour. The phenotypes are the same, black hair colour.

Answer 3

see in HH both alleles code for black hair so obv the phenotype is black hair. but in Hh genotype which is heterozygous H which is dominant masks the expression of the reccessive allele. thus the name dominant. so here black colour wins over brown colour. so you get the same phenotype.
