Chapter 11.4 Meiosis Flashcards
Diploid
Cell that contains 2 sets of homologous chromosomes
Haploid
Cell that contains only 1 set of chromosomes
Meiosis
Process of producing gametes through a reduction of chromosome numbers in cells
Crossing-over
When homologous chromosomes exchange portions of their chromatids during meiosis
Zygote
Fertilized egg
Tetrad
A structure containing 4 chromatids (pair of homologous chromosomes)
What types of cells are produced during mitosis?
Body
What types of cells are produced during meiosis I?
Sperm/Egg
What types of cells are produced during Meiosis II?
Sperm/egg
What type of cell is in Mitosis?
Body cells?

Sex cells
What type of cell is in Meiosis II?
Sex cells
Genetics of daughter cells in mitosis?
Clones/identical to mother cell
Genetics of daughter cells in meiosis I?
Genetically different

Genetically different
Purpose of division in Mitosis?
Cell repair and cell growth
Purpose of division in Meiosis I?
Sexual reproduction
Purpose of division in Meiosis II?
Sexual reproduction
Number of daughter cells at the end of Mitosis
