What is the science that study heredity?
GENETICS
Is a concept you may have learned about in math class
PROBABILITY
Which conditions can affect gene expression and influence genetically determined traits?
ENVIROMENTAL CONDITIONS
Meaning "one set"
HIPLOID
Prophase II Methaphase II Anaphase II Telophase II and Cytokinesis are phases of _____.
MEIOSIS II
Which is the process that during,male and female, reproductive cells join to produce new cells?
FERTILIZATION
Organisims that have two identical alleles for a particular gene
HOMOZYGOUS
Traits controlled by two or more genes are said to be ____________.
POLYGENIC TRAITS
Two sets of chromosomes are _____.
HOMOLOGOUS
The final for phases of meiosis II are similar to those in _________.
MEIOSIS I
Th different forms of a gene is called...
ALLELES
Which is one of the best ways to predict the outcome of a genetic cross by drawing a simple diagram
PUNNET SQUARE
Gene with more than two alleles is said to have ______.
MULTIPLE ALLELES.
A cell that contains both sets of homologous chromosomes is said to be....
DIPLOID
Contains four chromatids.
TETRAD
What states the principle of dominance?
That some alleles are dominant and other recessive.
States that genes for different traits can segregate indepenly during formation gametes.
INDEPENDENT ASSORMENT
The phenotypes produced by both alleles are clearly expressed.
CODOMINANCE
Process in which the number of chromosomes per cell is cut in half through the separation of homolgous chromosomes in diploid cells.
MEIOSIS
In mitosis when two sets of genetic material separate, each daughter cell recieves _____.
ONE COMPLETE SETS OF CHROMOSOMES
What happens during gamete formation?
The alleles for each gene segregate from each other.
Observed through patterns of inheance, form the basis of modern genetics.
MENDEL´S PRINCIPLE OF HEDERITY
Cases in which one allele is not complety dominant over another are called ______.
INCOMPLETE DOMINANCE
Phases of meiosis I
Prophase I
Methaphase I and Anaphase I
Telophase I and Cytokinesis
__________ does not normally change the chromosome number of the original cell.
MITOSIS
