The possibility that whether the unaffected female can have female offspring with red-green colorblindness. Concept introduction: The traits can be defined as the phenotypic characteristics that are coded by the genes. The genes coding for the traits can be present in X chromosome, Y chromosome or the autosomes. The traits are inherited as autosomal recessive, autosomal dominant, X-linked recessive, X-linked dominant traits or Y linked traits. There are certain traits which are influenced or limited to one sex. The red-green colorblindness is an X-linked recessive trait.

Fig. 1: The possible genotype and phenotype of the progeny produced by the unaffected female.

Explanation:

The X-linked recessive diseases are expressed in males who have one mutant allele, as the males have only one X chromosomes. The females having two mutant alleles of X-linked disease will be affected by it. The heterozygous females (carrying one mutant allele) will be normal but they will be the carrier.

If the father of the unaffected female would be affected, then all the daughters will be the carrier of the trait. A colorblind father will have all the carrier daughters. If the carrier female marries a colorblind man, then half of the daughters will be affected.

Conclusion

In case, if the father of the unaffected female would have been affected, then all of his daughters would be carrier. If the carrier female marries a colorblind man, then half of her daughter will be affected.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
