Genetics Review

What is the genetic makeup of the offspring of asexual reproduction?

• Genetically identical to parent

• Genetically different from parent

• Genetically different from grandparent

If a heterozygous parent and a homozygous recessive parent mate, what percentage of their offspring will be dominant?

• 25%

• 50%

• 75%

• 100%

Asexual Reproduction involves _____ parent.

• 2 parents

• 0 parents

• 1 parent

• 3 parents

When an offspring grows off from the body of a parent organism it is called __________________.

• budding

• fission

• fragmentation

• sporulation

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -

• makes its own food
• is unicellular
• live in a marine habitat
• reproduces asexually

In plants, tall (T) is dominant to short (t). Perform the following cross: Tt x Tt. What is the probability of producing a short plant?

• 0%
• 25%
• 50%
• 75%

What are some of the facts about asexual reproduction?

• Takes only one mate to reproduce and takes a longer time to reproduce
• Takes a shorter amount of time to reproduce and it takes two mates to reproduce
• Reproduces diverse offspring and takes a longer time to reproduce
• Takes only one mate to reproduce and takes a shorter time to reproduce

What term denotes the physical expression of a gene?

• genotype

• phenotype

• appearance

• homologous

What is one disadvantage of sexual reproduction?

• Only one parent needed
• Off spring are exact copies of parents
• Happens very quickly
• Needs two parents

Hydra reproduce by

• binary fission

• budding

• sexual reproduction
