What is the scientific term that refers to sex cells?

• autosome

• gamete

• karyotype

• chromosome

This term refers to half the normal chromosome number

• haploid

• 2N

• diploid

• 3N

The exchange of genetic information that insures that every gamete is unique is referred to as

• mitosis

• meiosis

• reduction division

• crossing over

All sperm and egg cells are genetically identical.

• TRUE

• FALSE

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

HOW MANY CHROMOSOMES DO HUMAN GAMETES HAVE?

• 46

• 23

• 47

• 22

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

THIS IMAGE SHOWS WHAT IS HAPPENING WITH THE CHROMOSOMES?

• NON- DISJUNCTION

• METAPHASE

• TELOPHASE

• CROSSING OVER
