Genetics & Mendel

Ch 12 Inheritance/Meiosis

QuestionAnswer
The scientific study of biological inheritance Genetics
process of sexual reproduction in which male and female reproductive cells join to form a new cell fertilization
specific characteristic of an individual trait
offspring of crosses between parents with different traits hybrid
sequence of DNA that codes for a protein and thus determines a trait; factor that is passed from parent to offspring gene
one of a number of different forms of a gene allele
Mendel’s second conclusion, which states that some alleles are dominant and others are recessive principle of dominance
separation of alleles during gamete formation segregation
sex cell with haploid number of chromosomes gamete
exhibits the dominant trait Capital letter genotype dominant allele
the trait that can be masked by the dominant trait known by lowercase letter recessive allele
the likelihood that a particular event will occur probability
having two identical alleles for a particular gene homozygous
having two different alleles for a particular heterozygous
physical characteristics of an organism phenotype
genetic makeup of an organism genotype
diagram that can be used to predict the genotype and phenotype combinations of a genetic cross Punnett Square
one of Mendel’s principles that states that genes for different traits can segregate independently during the formation of gametes Principle of Independent Assortment
situation in which one allele is not completely dominant over another allele incomplete dominance,
situation in which the phenotypes produced by both alleles are completely expressed Codominance
a gene that has more than two alleles multiple alleles
trait controlled by two or more genes polygenic traits
type of chromosomes in which one set comes from the male parent and one set comes from the female parent homologous Sounds like "home-ah-lo-gus"
a cell that contains two sets of homologous chromosomes (2n) diploid
a cell that contains only a single set of genes (n) haploid
process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell Meiosis
structure containing four chromatids that forms during meiosis or homologous pair of chromosomes tetrad
process in which homologous chromosomes exchange portions of their chromatids during prophase I of meiosis or segments of non-sister chromatids break and reattach to the other chromatid crossing-over
Genotype with 2 dominant alleles (Ex: TT) Homozygous Dominant
Genotype with 1 dominant allele and one recessive allele (Ex: Tt) Heterozygous
Genotype with 2 recessive alleles (Ex: tt) Homozygous Recessive
maternal mother
paternal father
female gamete or female sex cell egg cell (ovum)
location or position of a gene locus
first 22 pairs of homologous chromosomes autosomes
the 23rd (or last) pair of homologous chromosomes sex chromosomes
male gamete sperm cell
process of production and maturation of sperm Spermatogenesis Sounds like "sperm-at-o-gen-uh-sis
Process of production and maturation of egg cell (or ovum) Oogenesis Sounds like "o-o-gen-uh-sis"
Type of human body cell with the "normal" amount of chromosomes (2n) Somatic cells
two chromatids joined by a common centromere sister chromatids
chromatids of the other chromosome of a homologous pair non-sister chromatids
location of crossing over or location where chromosomes touch each other and exchange genes Chiasmata (chiasma) Sounds like "khi-as-mata"
female sex chromosome XX
male sex chromosome XY
egg cell and sperm cell fuse together to form a zygote
the process of the egg cell (ovum) and sperm cell fusing fertilization

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
