In the Beginning
What’s theDiff?
In the Garden
With Mendel
I KnowWhat UMean
IngredientsFor
Genetic Soup
2
Set of instructions for characteristics passed
from parent to offspring.
3
What are genes?
4
Passing of traits from parent to offspring
5
What is heredity?
6
Where do your genes come from?
7
What is one set or allele from each parent?
8
The number of chromosomes in a human
sex cell (egg or sperm)
9
What is 23?
10
Why siblings look different from one
another (if they are not identical twins).
11
They inherit different chromosomes with different alleles?
12
The difference between genotype and phenotype
13
A genotype is the inherited combination of alleles (the letters). The
phenotype is the organism’s appearance
(what it looks like)
14
The difference a dominant trait and a recessive trait
15
A dominant trait has more influence and will appear
with just one allele. A recessive trait must have
two alleles to appear.
16
The difference between a hybrid and a purebred
17
A hybrid has two different alleles or genes for a trait.
A purebred has two of the same allele or gene
for a trait.
18
The difference incomplete dominance and co-dominance
19
Incomplete dominance blends two traits (like white and red flowers
make pink). In co-dominance, both alleles
have equal influence and both show (like AB type
blood).
20
The difference between a sex cell and a body cell
(in genetics).
21
A sex cell has half the genetic material and is combined with another
sex cell to pass on genetic information in
reproduction. A body cell has complete set of
chromosomes and is not passed on to offspring in
sexual reproduction
22
Mendel used this type of genotype as the parent
generation for investigating a trait.
23
What is true-breeding or homozygous
24
The type of offspring that Mendel found after
crossing a homozygous dominant and
homozygous recessive plant for each trait
25
What are hybrid or heterozygous ?
26
The ratio of dominant to recessive when you cross
two plants that are heterozygous for a trait
27
What is 3 dominant to 1 recessive?
28
Mendel is known as the father of this area of
science
29
What is heredity?
30
What Mendel discovered.
31
What is traits can be dominant or recessive
and are inherited in predictable patterns?
32
Differences in organisms that are seen in a
population
33
What are characteristics?
34
Two forms of the gene for a trait
35
What is an allele?
36
An organism’s combination of alleles
37
What is a genotype?
38
A diagram of a family history used to trace a
trait through generations
39
What is a pedigree?
40
When each allele for a trait has its own degree of influence on appearance
and creates a “blend”
41
What is incomplete dominance?
42
These are different forms of a characteristic
43
What is a trait?
44
The reason identical twins have the same genotype
45
What is they have the same set of alleles
46
The kind of cells that have alleles you pass on to
offspring
47
What are sex cells?
48
Factor that can influence traits
49
What is the environment
50
Traits on sex chromosomes that show up in males most of the
time
51
What are sex-linked traits(because males have xy
for the 23rd chromosome)?
