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? ½½
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. SS S s s S Ss ss
