Some genes can be hidden or covered up by another. These are considered to be-
Recessive
100

What are alleles?

alternate forms of the same gene

200

Where are genes located?

In the chromosomes (nucleus)

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

A DNA strand reads TGA–CCT. What is the complementary DNA strand?

ACT-GGA

200
What is the punnet square used for?
To determine the outcome of genetic crossings.

A black chicken (BB) is crossed with a black chicken (BB). What percentage of offspring will be black?
100%
300

What is incomplete dominance?

When neither allele is fully dominant, resulting in a blended phenotype

How did Rosalind Franklin help other scientists?

Her X-ray image revealed DNA’s double-helix structure

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%

What is codominance?

When both alleles are expressed equally and visibily in the phenotype

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

Genotype

A DNA sequence is TAC–GGA–TTC. What is the mRNA strand made during transcription?

A DNA sequence is TAC–GGA–TTC. What is the mRNA strand made during transcription?

Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color?
Dark brown is dominant and white fur is recessive. Both parents are heterozygous.
