Jenna has a genetic disorder. Her husband Jeff does not. Jeff and Jen have 20 offspring - all ten of their girls do not have the disorder, but all ten of their boys do.

• this disorder is a sex linked trait

• this disorder is an complete (Mendelian) dominant trait

• this disorder is a recessive trait

• this disorder is an incomplete dominant trait

• this disorder is a poly-genetic trait

This karyotype...

• has 46 chromosomes
• is of a normal female
• shows an inherited disease passed from parent to offspring
• is a result of nondisjunction

Females with this trait will always pass this to their offspring, males with the trait never pass to offspring. 

• this is a complete dominant trait
• this is a sex linked trait
• this is a trait in the mitochondria
• this trait is incomplete dominant

The world wide average height today is 3 inches taller than 100 years ago.. MOST likely due to

• new mutations (new alleles) that have arrisen in the population

• sexual selection - females always choose taller men

• better nutrition today than 100 years ago

• random genetic drift

A cross between a dihybrid individual (heterozygous for two traits) and a homozygous recessive individual for the same two traits produces these phenotypes as offspring: parental phenotypes 526 and 542, and recombinant phenotypes 22 and 24.

• these genes sort independantly
• these genes are linked
• these genes are not linked
• these genes are on different chromosomes

Winter wheat can grow in a variety of temperatures. Winter wheat in very cold temps...

• will have very little cholesterol in the cell membrane
• will have mostly unsaturated fatty acids in the cell membrane
• will have mostly saturated fatty acids in the cell membrane
• will have a very rigid cell membrane

All of these are possible ways for new genes to come about in a population EXCEPT

• random mutation
• gene duplication
• natural selection

An entire nest of turtles hatches - they are all females! This is most likely because...

• sex determination in turtles is totally random
• sex for turtles is due to chromosomes given in fertilization
• turtles are all clones of the mother
• sex determination in turtles is due to environment
