Intro to genetics
when certain characteristics are passed down from parents to children, examples are eye color, hair color, height, and skin
Heredity
the study of genes, genetic variation, and heredity in organisms. It is an important branch in biology because heredity is vital to organisms' evolution.
Genetics
AA Is an example of…
Homozygous genotype
CAPITAL LETTER (A)- brown eyes
Dominant allele
In a cross between a homozygous dominant parent and a homozygous recessive parent, what is the chance of the offspring having the dominant phenotype?
100%
This scientist was born in 1822, he is considered the father of genetics, he studied inheritance with peas, and found that certain traits are passed down
Mendel
Alleles
Aa is an example of
heterozygous genotype
lowercase letter(a)- blue eyes
Recessive allele
inheritance pattern when both alleles are expressed equally in the phenotype of a heterozygote?
Codominanice
This experiment studied peas, dr Mendel created it, and the results were that certain genes will get passed down and some won’t.
Mendel‘s experiment
______ always expressed if passed down (A) and ______ is only expressed when there are no dominants (a)
Dominent and recessive
How manytraits are observed whenusing a monohybrid punnett square
one
What will you get if your parents are Homozygous dominant AA or heterozygous Aa
Brown eyes
True or false, Your height and skin color are not just due to your genes.
True
Where do children get their genes from?
Parents genes
______ means that you inherited two identical alleles and ______ heterozygous is when you inherent two different alleles
Homozygous and heterozygous
How are recessive alleles represented
a (lowercase letters)
What will you get if your parents are homozygous recessive aa
Blue eyes
allele that is not expressed in a heterozygote
Hybrid
affects how genes are passed down from parent offspring
Meiosis
______ is the detectable expression and ______ is the dna sequence
phenotype and geneotype
How are dominent alleles represented
A (UPPERCASE LETTERS)
How you determine how children got their genes
Punnett squares
This law states that factors controlling different characteristics are inherited independently of each other.
The law of independent assortment
