Meiosis
What type of reproduction is meiosis used for
Sexual reproduction
Who first studied the inheritance of traits?
Gregor Mendel
Different versions of the same traits are called _____.
alleles
What are Punnett squares used for?
To determine all possible genotypes and phenotypes of offspring
What do pedigrees show?
Inheritance of traits through generations
How many products are formed in meiosis? What are these products called?
4 gametes
What type of pea plants did Gregor Mendel use in his first cross (Parental Generation)
True breeding pea plants (purebred)
What is the difference between genotype and phenotype?
genotype = genes/ allele combination
phenotype = physical observable trait
A grey bunny was born from a black bunny and a white bunny. What pattern of inheritance is this? What is the genotype of the grey bunny?
Incomplete dominance/Heterozygous
females = circles
Compare the amount of genetic material in the beginning and end of meiosis I?
start: 2n-diploid
end: n-haploid
The F1 (first filial) of pea plants were considered _________.
Hybrid
Some traits can be masked by others. These traits are called ____?
Recessive
A man who is a hybrid and has Brown eyes, marries a woman who is blue eyed? What is the probability of having a blue eyed baby?
50%
What do unshaded individuals represent?
Individuals without the trait in question
What phase does crossing over occur?
Prophase I
What does the Law of Segregation state?
Alleles segregate into separate alleles
Alleles that always code for a functional protein are called
Dominant alleles
A man with blood type AB, marries a woman with blood type O. What is the probability they will have a baby with type A blood?
50%
A shaded circle marries a shaded square and they have an unshaded circle. Is the trait dominant or recessive?
Dominant
In metaphase II _________ line up at the metaphase plate
sister chromatids
What does the Law of Independent Assortment State?
Alleles separate into individual gametes randomly
Where are alleles/genes located?
On chromosomes
In rabbits long ears are dominant (E) to short and brown fur (F) is dominant to white fur. If a short eared white rabbit is crossed with a rabbit that is heterozygous for both traits, what is the probability of having a rabbit with long ears and white fur?
25%
An unshaded circle marries an unshaded square and they have a shaded circle. What are the genotypes for the parents?
Heterozygous
