Genetics and Heredity

What is heredity?

• the production of protein for an organism's energy needs

• the passing of genetic material from parents to offspring

• the removal of wastes from an organism's cells

• the relaying of information between parts of an organism

Genes are located in an organism's

• vacuoles

• lysosomes

• chromosomes

• ribosomes

Inherited traits are governed by

• digestive enzymes

• cell products

• blood cells

• genetic material

An organism inherits genetic material from its

• offspring

• food source

• parents

• environment

In which organelle are chromosomes located?

• nucleus

• cell wall

• lysosomes

• vacuole

Recessive alleles are expressed under which of the following conditions?

• every time they are found in an organism

• in green plants that reproduce through seeds

• when asexual organisms produce a pair of offspring

• only in the absence of dominant alleles for the same gene

The offspring of an organism produced through asexual reproduction is always

• genetically identical to its parent

• created by vegetative propagation

• made of cells with a cell wall

• different from its siblings

Asexual reproduction requires

• two parents

• only one parent

If two organisms reproduce sexually, their offspring will exhibit a genetic makeup that is

• identical to only one parent

• identical to all of its siblings

• a unique combination of traits

• the recessive traits from each parent

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.

• lives in a marine habitat.

• reproduces asexually.
