Boveri and Sutton's chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws …

Instead of assorting independently, the genes tend to "stick together" during meiosis. That is, the alleles of the genes that are already together on a chromosome will tend to be passed as a unit to gametes.

However, it wasn't until the early 1900s that the Boveri-Sutton Chromosome Theory linked Mendel's laws to the behavior of chromosomes during meiosis, solidifying the molecular basis of inheritance.

A The individual has a genetic condition caused by a single nucleotide substitution on chromosome 3. B The individual has a genetic condition caused by having X and Y chromosomes of different sizes. C …

This process is essential for growth and repair in the body. On the other hand, meiosis occurs in germ cells and produces four non-identical gametes with a haploid (n) number of chromosomes. These …

Understand how meiosis reduces chromosome number and creates variation through crossover and independent assortment. Explore the terminology of gametes, zygotes, haploid, and diploid states.

The diagram below shows how nondisjunction can take place during meiosis I if homologous chromosomes don't separate, and how this can lead to the production of aneuploid gametes (eggs or …

Understand how meiosis reduces chromosome number and creates variation through crossover and independent assortment. Explore the terminology of gametes, zygotes, haploid, and diploid states.

How XX human females (and other female mammals) shut down one of their X chromosomes in each cell. Disorders of sex chromosome number: Klinefelter, triple X, and Turner syndromes.
