What is the term used to describe the versions of a gene?

Allele

What is heredity?

The passage of genetic instructions (traits) from parent to offspring.

100
What is the punnet square used for?
To determine the outcome of genetic crossings.
100

How are traits passed from parent to offspring?

Through genes during reproduction

200

What are sections of DNA that code for traits called?

genes

200

Who first studied heredity and the passage of traits from one generation to the next?

Gregor Mendel

Asexual reproduction produces offspring that are genetically ____________ to the parent.
Identical

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the dominance of fur color genes?

Dark brown is dominant and white fur is recessive. Both parents are heterozygous.

200

How many parents are involved in asexual reproduction?

One


300

What are the bulky structures of DNA that carry genes called?

Chromosomes

300

What type of organism did Gregor Mendel use to first study heredity?

Pea Plants

300
If you are studying a population of genetically identical individuals, you can conclude that these individuals reproduce how?
Asexually
300

A black chicken (BB) is crossed with a black chicken (Bb). What percentage of offspring will be black?

75%

300

Why does a Punnet Square use capital and lowercase letters?

Capital = Dominant Trait

Lower Case = Recessive Trait

Mendel initially observed a parental generation, an F1 generation, and an F2 generation of plants. What does F1 and F2 mean?

F1 is the first generation of mated plants. F2 is the second generation.

For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-
Dominant
400
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?
25%
400
Some genes can be hidden or covered up by another. These are considered to be-
Recessive

What do we call the genetic make up of the individual, represented by a set of letters?
Genotype

How many total chromosomes do humans have?

46

What is the meiotic process that allows for multiple alleles to appear in offspring?

Crossing over

Long ears are dominant in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygous recessive, what is the only possible genotype of the offspring?

Ee

The physical trait observed in an offspring is known as its -
