What do we call two chromosomes in a nucleus that carry genes controlling the same inherited characteristics?
Homologous chromosomes or homologs are a pair of two chromosomes with the same length, centromere position, and staining pattern in a karyotype.
How many generations does it take to develop a new plant species by polyploidy?
Polyploidy can produce the antecedents of new species in one generation (autopolyploidy) or two generations (allopolyploidy) through the production of unreduced gametes or doubled somatic cells (Ramsey and Schemske, 1998; Mason and Pires, 2015).
Is cell division common in eukaryotes but rare in prokaryotes?
Cell division is common in eukaryotes but rare in prokaryotes. Prokaryotic chromosomes are more complex than those of eukaryotes. 8) Eukaryotic chromosomes differ from prokaryotic chromosomes in that they. A) are housed in a membrane-enclosed nucleus.
What are identical copies of chromosomes called?
Chromatid Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.
Which type of reproduction will result in genetically identical offspring?
Asexual Reproduction. Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent.
Which mutations would be passed onto future generations only if they occur in which type of cell?
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype.
Which of the following is likely to account for the difference between plant and animal cell cytokinesis?
Which of the following features likely accounts for the difference between plant and animal cell cytokinesis? Plant cells have two sets of chromosomes; animal cells have one set of chromosomes. Animal cells lack the microfilaments required for forming a cleavage furrow.
How does cell division differ in prokaryotes and eukaryotes?
The main difference between prokaryotic and eukaryotic cell division is that the prokaryotic cell division occurs through binary fission whereas the eukaryotic cell division occurs either through mitosis or meiosis. Furthermore, prokaryotic cells lack a nucleus while eukaryotic cells have a nucleus.
How do prokaryotic and eukaryotic chromosomes differ?
Eukaryotic chromosomes are located within the nucleus, whereas prokaryotic chromosomes are located in the nucleoid. The key difference between prokaryotic and eukaryotic cells is that eukaryotic cells have a membrane-bound nucleus (and membrane-bound organelles), whereas prokaryotic cells lack a nucleus.
