How did Mendel come up with his Principles of Heredity that affected science
He used probability and was the first to trace a trait through generations by observing the patterns of inheritance in pea plants
Why does mitosis always begin with a diploid cell and end up a diploid cell
Daughter cells need complete set of chromosomes to be identical.
An experimental technique that introduces virus genes into living cells to replace an abnormal, disease-causing gene
Gene therapy
When two alleles are different, they are said to be
Heterozygous
Who is the Father of Modern Genetics
Gregor Mendell
The physical appearance of an organism is called
Phenotype
Which type of cells undergo cell division
Both prokaryotic and eukaryotic cells
A visual tool used by Geneticists to trace inheritance through generations of family members
Pedigree
When two alleles are the same, they are said to be
Homozygous
A __________________________ occurs when a group of gene pairs acts together to produce a single trait
Codominance
This kind of allele will ‘cover up” the other allele and will be shown in the phenotype
Dominant
How did Mendel use probability to make his predictions
He worked with large numbers of plants, so he observed his chances of seeing a repeatable pattern to make predictions through Punnett square for future generations
The series of events that takes place from one cell division to the next is called ______________.
Cell cycle
This kind of allele will seem to “disappear” and is only shown if to of this same allele are present
This kind of allele will seem to “disappear” and is only shown if to of this same allele are present
The genetic make-up code of an organism is called _________________.
Genotype
