These are sections of chromosomes that code for a trait.

A gene

This is a characteristic that can be passed from parent to offspring.

Trait

What would device would you use to predict the possible offspring of a cross between different genotypes?

A punnett square

What is genetics?

The passing of traits from one parent to its offspring

How could you determine a person’s phenotype?

By looking at the person

The genetic make-up of an organism is called what?

Genotype

This type of allele in not fully expressed when paired with a dominant allele.

A recessive.

What do you call two alleles in a gene pair that are identical?

Homozygous

If you crossed a heterozygous individual with a homozygous recessive individual, what would the genotypes of their children look like?

Half would be heterozygous and half would be homozygous recessive

What do you call an organism that receives different forms of a genetic trait from each parent?

Hybrid or heterozygous

If you flip a coin, this is the probability you’ll get tails?

½

What are haploid cells?

Cells that contain half the amount of chromosomes

What phase of meiosis is this?

Anaphase II

What phase of meiosis is this?

Prophase I

What phase of meiosis is this?

Telophase II

What phase of meiosis is this? Metaphase II

What is a pedigree?

A graph that shows how traits are passed from generation to generation.

Does this statement occur in meiosis or mitosis: two cells are produced at the end.

Mitosis

Does this statement occur in meiosis or mitosis: the result is identical cells.

Mitosis

Does this statement occur in meiosis or mitosis: results in cells that have half the amount of chromosomes.

Meiosis

What are sperm cells and egg cells called?

Gametes

What do you call a cross made to study a single trait?

Monohybrid cross

Draw a punnett square for the following cross:• A heterozygous individual for straight hair is

crossed with a heterozygous individual for straight hair. Straight hair is dominant to curly hair. Use an “S” for the dominant trait.
