Cells are the basic unit of...

Life

100

True or False: Hereditary is the passing of traits from generation to generation. 

TRUE 

100

What letters are associated with homozygous dominant?

2 capital letters (ex: HH)

100

Dominant: 

Gene that is always expressed. 

200

True or False: One job of a cell is to clean up waste in the body.

True! Waste is produced while making energy

200

What is the difference between homozygous and heterozygous? 

Heterozygous means someone carries both traits (Bb), while homozygous means they only carry one trait (BB or bb).

200

True or False: It is possible for someone who has a dominant trait to have a baby that has the recessive version of the same trait. 

True

200

Recessive:

gene that is expressed only in the homozygous state

300

Genetic material in a cell can be found inside the...

Nucleus. 

300

What do chromosomes contain?

DNA

300

What do the letters on the outside of the punnett square stand for? 

The parents alleles/the parent's genetic information for a particular trait. 

300

Heterozygous: 

Genotypes made of two different alleles (Hh).

________________________ is the powerhouse of the cell. 

Mitochondria

What is the difference between a dominant and recessive trait? 

A dominant trait will always show if there is a dominant code in the persons DNA, but a recessive trait will only show if someone carries 2 recessive traits and no dominant. Dominant is the more common trait, where recessive is less common. 

400

In Guinea pigs, short hair (S) is dominant to long hair (s). What percent of short hair babies will a couple that has SS and ss as their alleles have?

100% short haired babies

400

Homozygous:

Genotypes made of the same alleles (HH or hh). 

500

Name 2 of the 3 main jobs cells have: 

Make energy, make protein and clean up waste.

500

Explain the difference between genotype and phenotype? 

A genotype is the organisms genetic information (Hh, hh, HH), while phenotype refers to an organisms observable physical traits. 

500

What is the probability of getting blue eyes with parents that have Bb and bb as their genotypes? 

50%

500

Alleles: 

different forms of genes for a single trait
