Interphase
What is the main focus of interphase?
To replicate the cells DNA
What are homologous chromosomes?
Pairs of chromosomes found in diploid organisms.
What happens to homologous chromosomes during metaphase I?
They align at the metaphase plate in two rows.
What part of interphase is crucial for DNA replication?
The s phase
What is crossing over?
Crossing over is the biological process during the meiosis I stage of cell division where homologous chromosomes exchange segments of genetic material, creating new combinations of alleles and increasing genetic variation in gametes (sperm and egg cells).
How is metaphase I different from metaphase of mitosis?
In metaphase I, homologous pairs line up, but in mitosis, individual chromosomes line up
What state are the chromosomes in during interphase?
They are in a relaxed, chromatin form.
What are tetrads?
A tetrad is a grouping of four.
What is the result of metaphase I?
It sets the stage for the separation of homologous chromosomes, creating genetic diversity through independent assortment.
