Meiosis

WHAT DOES MEIOSIS CREATE?

• CHROMOSOMES

• GAMETES

• DNA

• TRAITS

THE END RESULT OF MEIOSIS IS...

• FOUR UNIDENTICAL GAMETES

• FOUR IDENTICAL GAMETES

• TWO IDENTICAL GAMETES

• TWO UNIDENTICAL GAMETES

THE GAMETES ARE CONSIDERED TO HAVE ONE HALF OF THE GENETIC INFO SO IT IS CALL

• DIPLOID(2N)

• EUKARYOTE

• PROKARYOTE

• HAPLOID (N)

MALE GAMETE IS KNOWN AS

• EGG

• SPERM

A FEMALE GAMETE IS KNOWN AS

• EGG

• SPERM

CROSSING OVER ALLOWS FOR WHAT TO HAPPEN?

• ALL CELLS TO STAY THE SAME

• GENETIC VARIATION

• REDUCTION OF CHROMOSOMES

• CHROMOSOME NUMBER TO INCREASE

WHEN THE SPERM FERTILIZES THE EGG WHAT IS FORMED

• ZYGOTE

• EMBRYO

• FETUS

• FERTILIZATION

FERTILZATION IS ...

• THE FUSION OF A HAPLOID EGG AND SPERM

• THE FUSION OF A DIPLOID EGG AND SPERM

• THE FUSION OF A HAPLOID EGG AND DIPLOID SPERM

• THE FUSION OF TWO EGGS

THIS IMAGE SHOWS WHAT IS HAPPENING WITH THE CHROMOSOMES?

• NON- DISJUNCTION

• METAPHASE

• TELOPHASE

• CROSSING OVER

Chromosomes assort independantly, not genes because of the following

• The chromosomes contain the genes, genes can't leave the chromosome

• The genes contain the chromosomes

• It depends on the sex of the offspring

• In sexual selection of most organisms the genes will be directed by the DNA to assort independantly
