Why is meiosis important for sexually reproducing organisms? Why is meiosis important in sexual reproduction? A gene pool consists of When did gene pool first come into general use? How much of the gene pool is extinct? Why aren't all mutations recessive?
Why do diploid organisms need to have specialized sex cells? Why is meiosis important for sexually reproducing organisms? How are autosomes and sex chromosomes similar? When homologous chromosomes cross over, what is the result? Why do somatic cells divide by mitosis?
Functions. Homologous chromosomes are important in the processes of meiosis and mitosis. They allow for the recombination and random segregation of genetic
DNA is a molecule that converts an organisms genetic blueprint. Every person’s body has the same DNA. Apportion of your DNA is located in the cells nucleus, but a small portion of DNA can also be found in the mitochondria. The DNA structure is very important because it defines who we...
In particular, the large 'azygospores' that some Glomeromycotina produce are likely to be homologous to zygospores, the site of meiosis in other Mucoromycotina. The problem with these spores is that they are formed from multinuclear hyphae and yield a multinuclear spore – without a single ...
Monsoon is important becausee hold (i) Most of the rainfall occurs during the monsoon season. (ii) Rains bring relief especially after hot summer days. (iii) Sowing of many crops depends on the arrival of monsoon.
Knowing that all living things are made up of cells allows us to understand how organisms are created, grow, and die. That information helps us understand how new life is created, why organisms take the form they do, how cancer spreads, how diseases can be managed, and more. Cells even ...
This phenomenon-based unit explores the idea that though elephants are the largest land mammals and their massive bodies are made up of exponentially more cells than smaller organisms – cells that could mutate over their long lifespan – elephants rarely get cancer. Why is that?
meiosis. The formation of one crossover per chromosome pair is required for proper chromosome segregation. This “obligate” crossover is ensured by the major crossover pathway in plants, and in many other eukaryotes, known as the ZMM pathway. The secondary pathways play important roles also in...
(referred to as epigeneticmarks), but also include other mechanisms. Epigenetic marks are established during prenatal and early postnatal development and function throughout life to maintain the diverse gene expression patterns of different cell types within complex organisms but can also arise in ...
