Answer:
The correct option is A) will make no difference in the survival of life if there were major changes in the environment.
Explanation:
Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.
Answer:
Complete question:
We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the six modes of inheritance are consistent with this pedigree: Select one or more Y Linked Autosomal Recessive Autosomal Dominant X-Linked Dominant X-Linked Recessive We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder, Assuming the pedigree is accurate, indicate which of the six modes of inheritance ere consistent with this pedigree Select one or more X-Linked Recessive Y Linked Autosomal Recessive X-Linked Dominant Autosomal Dominant.
Answer:
After the analysis of this pedigree, it is clears that the inheritance pattern is X linked because the offsprings are affected with parents genotgype
Explanation:
The inheritance is X linked dominant because of the presence of one dominant gene for the affected genotype in male.
The male individuals are affected. This is therefore not a recessive inheritance in later case, it is only when the two genes are present at the same time the affected genotype will be seen.
Multifactorial disorder
Multifactorial disorders are
disorders that involve variations in multiple genes joined with environmental
causes. Diseases such as heart disease, type 2 diabetes, and obesity are multifactorial
disorder as they do not have single genetic cause but are caused by a
combination of environmental factors and life style with mutations in multiple
genes.
