Gene Linkage, Karyotypes & Chromosomal Mutations

Gene Linkage, Karyotypes & Chromosomal Mutations. Mendel's Flawed Principle. In fact not all genes independently assort ! An early example was found in sweet peas. Flower color and pollen length did not yield the expected 9:3:3:1 ratio in the F 2 . Instead a 23:1:1:9 was observed.

Types of Chromosome Mutations

Types of Chromosome Mutations. Aneuploidy (2n +/- m). Aneuploids differ from wild-type individuals by part of a chromosome set. Nondisjunction is a common mechanism for aneuploidy. Aneuploidy can be the cause of disorders such as Down Syndrome. Examples of Aneuploidy. Nullisomy (2n -2)

Mistakes in Meiosis

Mistakes in Meiosis. Nondisjunction. The failure of homologous chromosomes to separate properly during meiosis. What should happen. Nondisjunction. The results. If the abnormal gametes is fertilized the results. Polyploidy. the condition where cells have multiple sets of chromosomes

Non-invasive Prenatal Testing (NIPT) Market to Partake Significant Development By 2026

NIPT can also determine the gender of the fetus and NIPT is highly reliable in over 99% of Down syndrome cases.
