"Father of Genetics"
Who is Gregor Mendel?
200
two divisions occur during this process
What is meiosis?
200
different forms of genes; Gregor Mendel called these factors.
What are alleles?
200
a chart that shows all the possible ways alleles can combine in a genetic cross
What is a punnett square?
200
a sequence of DNA that determines a trait and is passed from parent to offspring
What is a gene?
200
if a dominant alles shows up int the genotype, the dominant trait will always show up
What is the law of dominance?
300
traits that are passed from parent to offspring and are part of our genetic code; Give an example.
What are inherited traits? Hair texture, natural hair color, natural eye color, height
300
having two different alleles for a particular gene; Give a genotype for height of plants.
What is heteozygous or hybrid? Tt
300
an organism's genetic makeup, or allele combination
What is a genotype?

the scientific study of heredity?
What is genetics?
300
a situation when an allele is not completely dominant (partitally dominant) over another allele. This causes a blending of alleles?
