Who observed that the behaviour of chromosomes at meiosis can serve as the cellular basis of both segregation and independent assortment?
1 Morgan and Boveri
2 Sutton and Boveri
3 Boveri and Brauer
4 W. Flemming
Explanation:
Walter Sutton and Theodore Boveri noted that the behaviour of chromosomes was parallel to the behaviour of genes and used chromosome movement (Figure 5.8) to explain Mendel’s laws.

Mendel’s law of segregation, is applied to the behaviour of chromosomes in meiosis, means that
1 Pairing of homologues will convert one allele into the other, leading to separation of the types.
2 Genes on the same chromosome will show 50% recombination.
3 Alleles of a gene will be linked and passed on together through meiosis.
4 Alleles of a gene separate from each other when homologues separate in meiosis I.
Explanation:
The Mendel’s law of segregation describes that the pair of alleles segregates from one anotherduring meiosis (i.e, while forming gamete) thus, only one allele is present in each gamete. Through this law Mendel stated that law of segregation is the first meiosis division in which the homologous chromosomes are segregated into daughter nuclei. It is based on the fact that every gamete contains only one allele.Thus, segregation takes place when the homologous chromosomes separate during meiosis in anaphase 1.
