Heredity & Adaptation - Investigation 1 & 2 Test

What is an allele?

• A copy of a chromosome

• A copy of a gene

• A copy of a histone

• A copy of a gentiger

What is a gene?

• A copy of an allele

• A segment of RNA found on a chromosome that determine the inheritance of two traits

• A segment of DNA found on a chromosome that determine the inheritance of a particular trait.

• A copy of a protein

DNA stands for:

• Deoxyrhino Neutral Antigen

• Deoxynecleic antihistamine

• Deoxyribbo neutrino antibody

• Deoxyribonucleic Acid

A dominant allele has:

• Less influence than other alleles

• The same amount of influence as other alleles

• More influence than other alleles

• No influence whatsoever

A recessive allele has:

• Less influence than other alleles

• More influence than dominant alleles

• The same influence as other alleles

• No influence whatsoever

Which one of the following genotypes is heterozygous?

• Aa

• EE

• aa

• Ee

What does heterozygous mean when we're talking about alleles?

• The alleles are the same, both are dominant

• The alleles are different: one is dominant, one is recessive

• The alleles are different, they are different letters

• The alleles are the same, both are recessive

Which one of the following genotypes are homozygous?

• AA

• Aa

• EE

• aa

What does homozygous mean when we're talking about alleles?

• The alleles are the same letter but one is dominant, one is recessive.

• The alleles are the same, they are either both dominant, or both recessive.

• The alleles are different letters, but there is always one dominant allele in the pair.

• The alleles are different letters, but always both dominant or both recessive.

What do we mean when we talk about genotype?

• The genetic makeup of an organism we can see, but not sequence.

• The genetic make up of an organism that we can sequence, but cannot see.

• The traits of different features we can physically see on an organism.

• All of the above
