Pass it On
The unit that determines traits. Mendel called these "factors."
What is a gene ?
The man whom history credits as the founder of heredity, or, genetics
Who is Gregor Mendel ?
An organism's complete genetic makeup. Or a specific genetic formation, such as a heterozygous form
What is a genotype ?
The physical appearance of an organism; the outer expression of its genotype
What is a phenotype ?
All traits are controlled by dominant and recessive alleles.
False
When the gametes (egg and sperm) connect during sexual reproduction
What is fertilization?
The stronger of the two kinds of alleles
What is a dominant allele ?
The likelihood that an event or offspring will occur
What is Probability?
The weaker of the two kinds of alleles
What is a recessive allele ?
What do you call a trait that is controlled by many genes?
Polygenic
Which of the following is a heterozygous genotype? AA Tt gg
Tt
The grid where we determine each possible genetic outcome an offspring may have
What is a Punnett square
A genotype that contains two of the same allele
What is a homozygous genotype ?
What information do we need before we can fill in a Punnett square?
The genotype of the female organism, the genotype of the male organism, and which alleles are dominant
When traits have more than 2 versions of the gene
What are Multiple Alleles ?
The odds of a heterozygous offspring when two heterozygous parents procreate
50%
The classification of this genotype: BB
What is homozygous dominant ?
What is the only was a recessive trait can show up?
When there are 2 recessive alleles
rr, bb, pp
What are the odds of a Tall plant (tall is Dominant) if you have a Homozygous Tall mother and a short father.
100%
If you have an XY chromosome, you are a
Male
The study of Heredity
What is Genetics?
When Mendel crossed pure-breeding tall plants (TT) with pure-breeding short plants (tt), what was the result?
All the plants were tall.
If a parent has the allele for hemophila (h), but is not a hemophiliac. What must his or her genotype be?
Hh
Gray eyes are a recessive trait. Cross a homozygous recessive mother and a heterozygous father. What are the odds of the child having gray eyes?
75%
