1. Use the following words to complete the sentence:

meiosis, budding, mitosis, binary fission.

 

Gametes, or sex cells, are formed by ​ (a)   while other eukaryotic cells like body cells are formed by ​ (b)   .

• meiosis
• mitosis
• budding
• binary fission

Match each term to its definition

• meiosis

• cell division that produces 2 diploid cells

• crossing over

• cell division that produces 4 haploid cells

• mitosis

• process where homologous chromosomes exchange segments of DNA

Select all the statements that correctly compare mitosis and meiosis

• Mitosis produces sex cells, meiosis produces all other cells

• Mitosis has 1 cell division while meiosis has 2 cell divisions

• Mitosis produces 2 daughter cells, meiosis produces 4 daughter cells

• Mitosis produces diploid cells, meiosis produces haploid cells

When meiosis is complete, how many haploid cells have been produced from the original diploid cell?

• 2

• 3

• 4

• 1

During what phase of meiosis does crossing over occur?

• prophase I

• metaphase I

• Prophase II

• Metaphase II

If the haploid cell of an organism contains 10 chromosomes, then the diploid cells of the organism will each contain how many chromosomes?

• 5

• 15

• 20

• 10

The chromosomes look different after DNA replication because they are made up of two sister ________________________.

What is significant about the process of crossing over, which is when homologous chromosomes exchange segments of DNA?

• It creates a complete set of chromosomes

• It contributes to gene flow among populations

• It provides genetic variation among organi

• It eliminates genetic disorders in most organisms

This diagram shows a process that occurs in the cells of living things. This process is called

Match each term to its definition

• chromatid

• either of the two strands of a chromosomes duplicated into identical parts after DNA replication

• zygote

• a paired set of homologous chromosomes formed during prophase I of meiosis

• tetrad

• fertilized egg that contains a complete number of chromosomes
