Mendel's work
A gene that is expressed phenotypically in heterozygous or homozygous individuals.
A gene that is phenotypically expressed in the homozygous state but has its expression masked in the presence of a dominant gene.
Organism with identical alleles/genes for a trait
What is Pedigree?
a genealogical table, chart, list, or record, especially of a purebred animal.
the principle stating that during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent.
which one allele does not completely dominate another allele, and therefore results in a new phenotype.
What is homozygous recessive?
Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
Organism with non identical alleles/genes for a trait
What is Codominance?
of or relating to two different alleles that are fully expressed in a heterozygous individual
Law of independent assortment is?
the principle stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together.
What is homozygous dominant?
if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.
any of several forms of a gene, usually arising through mutation, that are responsible for hereditary variation
Phenotype is?
the appearance of an organism resulting from the interaction of the genotype and the environment.
In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation.
If one parent has heterozygous,(Bb) tongue rolling and then other one has homozygous,(bb) non tongue rolling then what are the odds of the child not being able to tongue roll?
What is Homozygous?
having identical pairs of genes for any given pair of hereditary characteristics
Genotype is?
the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
If one parent has heterozygous,(Bb) cross fingers and then other one has heterozygous,(Bb) non crossing fingers then what are the odds of the child not being able to cross fingers?
What is Heterozygous?
having dissimilar pairs of genes for any hereditary characteristic.
What is Punnett Square?
in genetics, a type of grid used to show the gametes of each parent and their possible offspring; a type of grid that can indicate all the possible outcomes of a genetic cross.
