the homologous chromosomes exchange genetic material by the process of crossing over (seelinkage group). The homologous pairs line up along the midline of the cell inmetaphaseI and then separate inanaphaseI, with each pair being pulled to opposite ends of the cell. IntelophaseI theelongatedcell...
Crossing over is essential in increasing genetic variation. Metaphase I –Chromosomes line up at the equator of the cell, where the sequence of the chromosomes lined up is at random, through chance, increasing genetic variation via independent assortment. Anaphase I –The homologous chromosomes move...

What is the physical basis of crossing-over during prophase I of meiosis? Describe how events of meiosis and the fertilization of gametes result in genetic variation. Describe how the law of segregation and the law of independent assortment can be explained b...
This requirement can be explained by the failure of Sgo1 to localize to kineto- chores in the bub1∆ mutant84. In budding yeast, two kinetochore proteins, increased minichromosome loss (Iml)3 and chromosome loss (Chl)4, are required for the maintenance of centromeric cohesion in meiosis I ...

1) crossing over 2) independent assortment of chromosomes 3) random fertilization crossing over homologous chromosomes exchange pieces of genetic information and forms new genetic combinations independent assortment of chromosomes - every chromosome pair orients independently of the others ...
The loss of the central signal in mouse hybrids, in Dmc1–/– mice, and on the WT non-PAR X chromosome could potentially be explained if DSB repair is delayed. With a fixed on/off rate for PRDM9, the longer DSBs persist, the more time MRE11 may have to process and remove SPO11-...
Dihybrid crossover provides the basis for the principle of independent assortment. This implies how inside the particular entity, the heredity of the single sign is often irrespective of the heredity of all additional characteristics. The overall transmission of many characters at the same time, ...
