Difference Between Dominant Gene and Recessive Gene …
Co-dominance is the phenomenon wherein both the dominant and recessive allele expresses themselves in the same individual. … A cross between straight hair genes (homogeneous, SS ) and curly hair genes (homogeneous, ss ) will result in wavy hair (heterogeneous, Ss ). Note that in case of straight hair heterogeneous genes, Ss , the result will vary.
Dominant alleles are shown by capital letters. Recessive alleles by lower case letters. Example: The emoji gene for mouth shape has a dominant allele for a big smile (S), and a recessive allele for a small smile (s). Mum & dad both have big smiles (phenotype) but their genes are actually one of each allele (their phenotype is Ss ). parent mum …
Clinical characteristics of recessive and dominant congenital hyperinsulinism due to mutation(s) in the ABCC8/KCNJ11 genes encoding the ATP-sensitive potasium channel in the pancreatic beta cell. Oçal G(1), Flanagan SE, Hacihamdio?lu B, Berbero?lu M, Siklar Z, Ellard S, Savas Erdeve S, Okulu E, Akin IM, Atasay B, Arsan S, Ya?murlu A.
The answer would be:C. SsWhen you say heterozygous, this means that the trait has both dominant and recessive alleles for a specific trait. The genotype then will have a CAPITAL letter and a LOWERCASE letter as seen in: Ss.
There isn’t one genotypic ratio of one parent unless we know for sure the genotype of the other one. If the child is Ss, for example (S is dominant, s is recessive), then we know one of those came from one parent, the other one from the other. A few combinations of parental genotypes can result in this Ss in the child.
