A phenotype that requires only one set of genetic instructions to be produced is known as this What is dominant Category 1 - 100

The ABO blood type system is an example of this, where two different alleles both produce proteins and get expressed independently What is co-dominance? Category 1 - 200

The two alleles for a gene are found on these two DNA molecules What are homologous chromosomes?

This type of inheritance pattern (though relatively rare) would result in traits more likely to be expressed in females than males What is X-linked dominant?

Daily Double! Explain incomplete dominance at a molecular level What is heterozygotes produce fewer functional proteins so the phenotype is a blend? Or heterozygotes produce both proteins which lead to a blended phenotype Daily Double!

What the odds a two people with AB+- blood have a child with AB+- blood? What is ½*1/2 = ¼ or 4/16=1/4 IA IB AB + - +- A+ B+ A- B- AB+-

Two brown-eyed parents who are heterozygous in both genes mate Two brown-eyed parents who are heterozygous in both genes mate. This is the odds their child is green eyed What is 3/16

An individual with the genotype AaBbDdEeFF can produce how many unique gametes? (assume all genes on separate chromosomes) What is 24 = 16

Draw a cross for the mating of an AaBbDd mom and a AABbdd dad ABD ABd AbD Abd aBD aBd abD abd

Two genes affect the color of fur of a particular animal Two genes affect the color of fur of a particular animal. When two AaBb animals mate, 6/16 of them have gray fur. 1/16 have white fur while the rest have black fur. This is the most likely explanation for the presence of gray fur. What is producing the dominant phenotype in only 1 gene leads to gray fur (in both= black, in neither=white)

This is the only disease we covered in which either parent must have the disease to pass it on What is Huntington’s disease?

These two disorders are more common in males than females What are color-blindness and hemophilia?

This disorder occurs when both parents pass on defective instructions for an enzyme in the brain What is Tay-Sachs?

This is the reason sickle-cell anemia is so common in sub-Saharan African countries What is sickle-cell trait provides resistance to malaria (heterozygotes are at an advantage)

Cystic Fibrosis victims have a dysfunctional this What is CFTR protein or chloride ion channel protein?

The conversion of chromosomes from their unduplicated to duplicated (X) form occurs during this in both mitosis and meiosis What is interphase?

Homologous chromosomes are separated in this stage What is (anaphase I) of meiosis I

Daily Double! These are 3 differences between mitosis and meiosis Which cells go through process (stem cells vs. germ cells What cells are produced (somatic cells vs. gametes) # of cell divisions (1,2) # of daughter cells (2,4) # of chromosomes in daughter cells (all, half) Identical daughter cells vs. unique daughter cells Function (growth vs. reproduction) Daily Double!

A mosquito has 6 chromosomes in total A mosquito has 6 chromosomes in total. How many genetically unique offspring can two mosquitoes produce? 64. Each can produce 8 unique gametes PPP, PPM, PMP, PMM, MPP, MPM, MMP, MMM

The somatic cells of a koala have 16 chromosomes The somatic cells of a koala have 16 chromosomes. Sketch a Koala cell at metaphase of mitosis, meiosis I and meiosis II

This term describes two molecules of DNA that code for the same genes, but may contain different alleles What are homologous chromosomes

This type of inheritance can produce a wide range of phenotypes as opposed to either-or phenotypes What is polygenic or multigene inheritance

This term describes how one gene affects the expression of another gene and is a major reason for human genetic complexity What is epistasis

Identify 4 different inheritance patterns we have discussed Complete dominance Incomplete dominance Co-dominance X-linked Polygenic Epistatic

Genes are instructions for producing different proteins Genes are instructions for producing different proteins. Different genes must code for different sequences of these. What are amino acids?
