Question

Hemophilia, and color blindness are examples of _____ inheritance.

A. incomplete dominance

B. codominance

C. Sex linked inheritance

D. simple inheritance

Answer 1

Answer. C. Sex linked inheritance.

Explanation- Gene for hemophilia and colorblindness are present on X chromosome. The traits that are present on X chromosome are said to be sex linked. They are represented as Xh or XH alleles for Hemophilia gene and Xc or XC alleles for colourblindness gene.

In incomplete dominance, one allele can't completely express over another allele. Hence, a blended or intermediate phenotype is produced.

In codominance, both the alleles are expressed in a heterozygous condition. Hence, we can see both the phenotypes in the individual.

In simple inheritance, one allele is dominant over another allele and gets expressed in the phenotype.
