LE Bio Genetics & Inheritance

Which process and type of resulting cells are represented?

• mitosis, haploid gametes

• mitosis, body cells
• meiosis, haploid gametes

• meiosis, body cells

The process of crossing over, which increases variation, occurs in what phase of meiosis?

• anaphase 1
• prophase 1
• prophase 2
• telophase 1

The chromosomes that pair up during meiosis, are called __________ chromosomes.  

• homozygous 
• asexual
• homologous
• genes

What is a reason we need meiosis?

• So the offspring has the correct number of chromosomes from both parents

• So the offspring has genes from one parent
• So the offspring has genes from neither parents
• So the offspring makes its own genes
