Complex molecule that carries genetic information that defines an organism's traits. It is stored in the nucleus.
DNA
RNA
Protein
Glucose nucleic acid (GNA)
B = brown eyes
b = blue eyes
What is true about these two brothers that have brown eyes? James - Bb Carl - BB
A dominant trait
One has genetype and the other Bb
James inherited a dominant and recessive trait and can have green eyes or brown eyes while Carl inherited only dominant traits leading him to have brown eyes.
Carl inherited a dominant and recessive trait and can have green eyes or brown eyes while James inherited only dominant traits leading him to have brown eyes.
What is the difference between sexual and asexual reproduction?
Sexual reproduction makes identical offspring with only a single parent while Asexual reproduction needs a partner to make an offspring
Asexual reproduction needs a partner for an offspring
Sexual reproduction involves a partner to make an offspring while Asexual reproduction does not need a partner and makes identical offspring
There is no difference. They are the same thing
How is a heterozygous represented? How is a homozygous represented?
BB and BB
Heterozygous - bB Homozygous - Bb
Heterozygous and Homozygous cannot be represented
Heterozygous - Bb Homozygous - BB
An offspring inherit 23 chromosomes each from its mom and dad. If the offspring turns out to look more like the dad than the mom, how many chromosomes did the offspring inherit from the mom? Explain
47 - The offspring inherited more chromosomes from the dad than the mom causing the total chromosomes to increase.
24 - The offspring inherited more traits from their dad than their mom.
18 - The offspring inherited less chromosomes from the mom to look like the dad.
23 - Even if the offspring looks like one over the other, it would still have 23 chromosomes from its mom. The dad would have more dominant traits than the mom.
Who is the named the father of modern genetics? (HINT - The current unit, Classification, is based of that guy)
Gregor Mendel
Albert Einstein
Charles Darwin
Carl Linnaeus
What is the difference between phenotype and genotype?
They are both the same. They are the observable features of an organisms.
The difference between phenotype and genotype is that the phenotype is the observable characteristics of an organism. The genotype is the collection of genes within n organism
The difference between phenotype and genotype is that the phenotype is the collection of genes within an organism and the genotype is the observable characteristics of an organism.
A physical characteristic of an organism
Remember Gregor Mendel? What was the organism that he studied first? What were the characteristics that he studied about the organism
Food; taste, looks, shape, color
Pine tree; height, seed color, seed shape, seed coat color, and pod shape
Pea Plants; height, seed color, seed shape, seed coat color, pod shape
Bacteria; function, shape, size,
