9 important questions on Single-gene inheritance - The chromosomal basis of single-gene inheritance patterns - Single-gene inheritance in diploids
What is the two types of nuclear divisions that take place in eukaryotic cells?
- Mitosis
- Meiosis
What is mitosis and what are the phases?
- Interphase, chromosomes are laying in the nucleus
- Prophase, chromosomes duplicate
- Metaphase, chromosomes lay in the middle of the cell
- Anaphase, Chromatids are pulled apart
- Telophase, chromatids are pulled and the new cell memranes are formed.
- Daughtercells are created
What are the two identical copies, which are often visually discernible, called in mitosis?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is meiosis and what are the steps?
- Interphase
- Prophase I
- Metahase I
- Anaphas I
- Telophase I
- Prophase II
- Metaphase II
- Anaphase II
- Telophase II
- Gametes are created
What is the joining of the homologous pairs called?
Crossing over changes the combinations of alleles of several different genes. Does it directly affect single-gene inheritance patterns?
Apart from its allele-combining function, is crossing over is also known to be a crucial event that must take place in order for proper chromosome segregation in the first meiotic division?
Each of the four haploid cells that constitute the four products of meiosis contains one member of a tetrad; can the group of four cells be called a tetrad, too?
The spindle fibers that pull apart chromosomes are polymers of which molecule?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
