Biology Unit 5 Review 1

What is genetics?

• Study of heredity and how traits are passed to offspring

• Study of animals and survival of the fittest

• Study of how we look and why we look the way we do

• Study of health and diseases like fungal infections

Who is the father of genetics?

• James Watson

• Reginald Punnett

• Gregor Mendel

• Thomas Hunt Morgan

What is the dominant allele?

• The trait that is LEAST likely to show in Aa genotype

• The MOST important allele

• The LEAST important allele

• The trait that is MOST likely to show in Aa genotype

What is a phenotype?

• The alleles that are present in the offspring

• The type of gene

• How something looks compared with the genotype

• The letters that make up DNA

What is a pedigree chart used for?

• To track more complex genes

• To show inheritance throughout a family

• To aid doctors in solving difficult genealogical diseases

• All the Above

What does a fully colored square mean in a pedigree?

• The man is a carrier

• The man expresses the gene

• The woman is a carrier

• The woman expresses the gene

What is an example of Incomplete Dominance?

• Blue fuzzy and yellow fuzzy make blue fuzzy

• Blue fuzzy and yellow fuzzy make green fuzzy

• Blue fuzzy and yellow fuzzy make yellow fuzzy

• Blue fuzzy and yellow fuzzy make blue and yellow fuzzy

What is Codominance?

• heterozygous phenotype is a mixture of the two homozygous traits

• More than one possible allele with a hierarchy for most dominant

• Heterozygous genotype with a phenotype that shows both traits as specks, patches, and spots

• Genes that are controlled by the sex chromosome

Which of these qualifies as multiple alleles?

• Hair Color

• Blood Type

• Hair Texture

• All the Above

Which is an example of a sex linked gene?

• Eye Color

• Cystic Fibrosis

• Color Blindness
