Question

Which of the following are types of hereditary disorders?

Answer 1

Answer: A. single-gene and chromosomal

Hereditary disorder means it is passed from parents to offspring. It has different types based on its cause:  

1. Chromosomal abnormalities (damage to chromosomes)

2. Single gene defects ((monogenic disorder)

3. Multifactorial problems ( mutations in multiple genes )

4. Teratogenic problems (environmental factors)

Answer 2

Answer:

A. "single-gene and chromosomal".

Explanation:

Genetic dysfunctions may be hereditary, indicating that they are transferred down from the parents' genes. In different genetic disorders, deficiencies may be affected by new changes or modifications to the DNA. In such instances, the deficiency will only be transferred down if it befalls in the germline.

A single-gene ) dysfunction is the outcome of a particular mutated gene. Over 6000 human disorders are induced by single-gene defects. Single-gene dysfunctions can be moved on to the following generations in various ways. Genomic imprinting and uniparental disomy, though, may influence inheritance models.

A chromosome deformity is a lacking, more, or irregular part of chromosomal DNA. It can be of an atypical amount of chromosomes or a fundamental deformity in one or more chromosomes.
