Biology Quiz Mitosis + Meiosis + Mountain Lions 3.5.25

Mitosis

A process where a cell copies itself to make 2 identical cells

This process is important because it replaces damage/repairs worn out cells

Meiosis

process that contributes to genetic variety (gametes/sperm or egg cells)

Gamete cells only have 23 chromosomes each

Interphase

1. cell is growing

2. Replicating DNA

3. carrying out cell process

4. Is the first step before meiosis

Homologous Chromosomes

1. same size

2. contains same type of genes in the same location

3. they match together

Crossing over

important process that only happens in the meiosis and alleles are exchanged between homologous chromosomes creating new variations

cell division

cell divides to create new cells (mitosis + meiosis)

Diploid

Nucleus with a full set of chromosomes and homologous (mitosis)

Haploid

Nucleus with half of the normal chromosome number (meiosis)

Zygote

fertilized egg cell, produced when a egg nucleus and sperm nucleus combines (diploid cell)

Sexual Reproduction

two parents combine their DNA to create an offspring (two haploid gametes combines to create one diploid zygote)

Genetic Diversity

many variations and different traits that can be helpful
