Genetics I

When the result is two cells with the same number of chromosomes as the parent cell, this is called:

• Meiosis

• Mitosis

• Photosynthesis

• Respiration

What is the disorder when a group of abnormal body cells begin to go through cell division at a rapid rate?

• Albinism

• Cancer

• Hemophilia

• Color blindness

The purpose of mitosis is:

• Sexual reproduction

• To make gametes

• Tissue repair

• To create genetically diverse cells

Humans have 46 chromosomes, how many come from each parent?

• 46

• 92

• 12

• 23

If a dog has 78 chromosomes, how many are in a dog's sperm cell?

• 78

• 38

• 156

• 46

What process occurs in sexual reproduction?

• Respiration

• Binary fission

• Joining of sex cells

• Photosynthesis

Which of the following describes asexual reproduction?

• No sex cells are joining

• It involves two parents

• There is genetic variation

• Involves production of egg and sperm

Organisms that are produced asexually, have offspring that will be:

• Genetically different from each other

• Produced through fertilization

• Produced by joining of gametes

• Are genetically identical to the parent

Where is hereditary information found?

• Genes found on chromosomes

• Chromosomes found on genes

• In the mitochondria

• In the ribosomes of gametes

Gregor Mendal came up with some ideas about genetics by:

• Breeding mice in a lab

• Observing fruit flies

• Crossing pea plants

• Culturing bacteria in lab
