Meiosis 2nd half- Other half is on Lauren's Flashcards
How are diploid numbers restored in an organism?
Diploid numbers are restored through fertilization to form a diploid zygote.
What is the purpose of haploid cells in mammals?
Haploid cells are crucial for sexual reproduction.
What processes lead to chromosomal abnormalities within a single chromosome?
Errors during DNA replication and repair, deletions, duplications, inversions, or translocations.
What process leads to additional chromosomes in a gamete and thus offspring?
Nondisjunction.
What is the end result of meiosis II?
4 daughter cells
Each one is genetically unique.
Are the daughter cells from meiosis II haploid or diploid?
Haploid
In a human cell, how many autosomes and sex chromosomes are there?
22 autosomes, 1 sex chromosome
What are the end results of mitosis?
Diploid somatic cells (identical)
What are the end results of meiosis?
Haploid gametes (genetically unique)
How do the processes of mitosis and meiosis differ in terms of cell divisions?
Mitosis has 1 cell division, while meiosis has 2 cell divisions.
What are key features of meiosis that does not occur in mitosis?
Crossing over and formation of homologous pairs.
In which type of cells does mitosis occur?
Somatic cells
In which type of cells does meiosis occur?
Germ cells
What type of cells does mitosis create?
Somatic cells
What type of cells does meiosis create?
Gametes
