Front

DNA is made of:

Back

Genes

Answer explanation

DNA is composed of genes, which are segments of DNA that code for proteins. While chromosomes are structures that contain DNA, the correct answer specifically refers to the building blocks of DNA, which are genes.

Front

Genes are inherited from mom and dad in what ratio?

Back

50% mom / 50% dad

Answer explanation

Genes are inherited equally from both parents, resulting in a 50% contribution from mom and 50% from dad. The option '100% single mom' is incorrect as it implies no contribution from the father.

Front

Genes contain your?

Back

traits

Answer explanation

Genes contain your traits, which are characteristics passed from parents to offspring. These traits can include physical attributes, behaviors, and other inherited features, making 'traits' the correct answer.

Front

What are the colored bands on the chromosome called?

Back

genes

Answer explanation

The colored bands on chromosomes represent genes, which are segments of DNA that code for proteins and determine traits. Alleles are different forms of a gene, but the bands themselves are specifically called genes.

Front

genetic combination

Back

genotype

Answer explanation

The term 'genotype' refers to the genetic combination of an organism, encompassing the specific alleles inherited from its parents. In contrast, 'phenotype' describes the observable traits resulting from the genotype.

Front

Spongebob's phenotype is a _________ body color.

Back

Yellow

Answer explanation

Spongebob is known for his bright yellow color, which is a defining characteristic of his appearance. Therefore, the correct answer is 'Yellow'.

Front

What is the correct phenotype for this organism?

Back

blue body color

Answer explanation

The correct phenotype for this organism is 'blue body color' as indicated in the answer choices. The other option, 'green body color', is incorrect.

Front

Which of these is an example of a phenotype?

Back

Blue eyes

Answer explanation

A phenotype refers to the observable traits of an organism. 'Blue eyes' is a visible trait, making it a phenotype. In contrast, 'BB' represents a genotype, which is the genetic makeup and not directly observable.

Front

Genotype for blue eyes

Back

bb

Answer explanation

The genotype for blue eyes is typically represented as 'bb', indicating two recessive alleles. 'BB' would represent brown eyes, as brown is dominant over blue.

Front

An example of phenotype.

Back

long neck

Answer explanation

A phenotype refers to the observable traits of an organism. 'Long neck' is a clear example of a phenotype, while 'LL' represents a genotype, which is not observable.
