2
This Austrian Monk is known as the Father of modern Genetics.
3
Who is Gregor Mendel
4
In his study of heredity Mendel used this type of plant.
5
Pea Plant
6
Through his research Mendel developed this.
7
The first workable model of how genetics works
8
The pea plant was ideal for Mendel’s Research because they had these features. (list three)
9
Tall and Short, Smooth and wrinkled seeds, and Complete flowers
10
In order to perform his experiment Mendel need to have this type of strain of plants
11
Purebred
12
Define: Law of Dominance
13
Certain traits are dominant and appear to make recessive traits disappear.
14
Define: The Law of Independent Assortment
15
Factors (genes) for certain characteristics are passed from one generation to the next independently from other traits
16
Define a Dominant Trait
17
Expressive allele, indicated by a capital letter.
18
Define a Recessive trait
19
The genes do not express themselves; these are represented by lower case letters
20
Define Probability
21
The likelihood that some outcome will occur
22
Chromosome
23
Rod shaped bodies that occur in pairs, carry the genetic make up
24
Genetics
25
The study of how traits are passed
26
Genes
27
Heredity units located on the chromosome
28
Homozygous
29
Condition in which two alleles in a given location are the same
30
Heterozygous
31
Condition when two alleles at a given location are different
32
Define Genotype
33
The Genetic composition of an individual
34
Define Phenotype
35
How an allele expresses itself, what it looks like
36
Is the following gene set Heterozygous or Homozygous BB
37
Homozygous
38
If you see a black cow standing in a field, do you know its phenotype or genotype? How? (Black is dominant)
39
The phenotype is black (what it looks like)
The phenotype is black (what it looks like). You know that it has at least one black gene, but you cannot know the rest of its genotype.
40
Define Meiosis
41
Process of cell division that produces gametes, having a haploid number of chromosomes
42
The shape of DNA is called a
43
Double Helix
44
List the four Nitrogen bases (full names)
45
Adenine, Guanine, Thymine, Cytosine
46
Which nitrogen bases are purines?
47
Adenine & Guanine
48
How do the bases pair?
49
A-T & C-G
50
Which parent controls the gender of offspring and why?
51
Male, because his chromosomes are XY and the female is XX meaning whatever the male passes becomes the new offspring's gender
