Exam 6: Patterns of Inheritance

We need a hammer to pound nails into a board.Even if we have the nails,we cannot pound them without first getting hold of a hammer.This is similar to the genetic relationship known as

A Punnett square charts the separation of alleles into ________.

Would it be necessary to have both the genotype and phenotype for an organism if you are attempting to predict the inheritance pattern for a trait,such as hair color,in offpsring?

The observation that individuals afflicted with albinism also always have vision problems is an example of

The figure shown indicates two diseases with genetic links that are common in industrialized nations.The fact that both are about 80-90% avoidable indicates that

Which of the following might explain how two separate genes control a single trait?

MATCHING Match each mode of inheritance to a statement listed below. -A parent with curly hair and a parent with straight hair produce a child with wavy hair.

Which of the following statements explains how genetically identical plant clones can exhibit dramatic phenotypic variation?

If two different alleles for the same trait have an equal effect on the phenotype,the alleles are

One of the first medical tests a newborn receives determines if the child has phenylketonuria (PKU).PKU is the result of a mutation in a single gene that causes mental retardation and a host of other phenotypes (light hair and skin color,eczema,and a "mousy" smell).By detecting PKU early,doctors are able to reduce the effect of this condition with a modified diet.PKU is an example of

If you compare a sperm cell in a human to a skin cell from the same individual,which of the following differences would you expect to find?

In Mendel's controlled mating experiments the individuals produced by crossing two true-breeding parents are referred to as

A single gene with one dominant allele for black hair (B)and one recessive allele for brown hair (b)controls hair color in mice.A male mouse with black hair mates with a female mouse with brown hair and they have 12 offspring.Are you able to determine the predicted ratio of hair color in their offspring using a Punnett square? Explain your answer.

Which of the following statements is NOT true?

What is the smallest number of traits that are needed to test Mendel's law of independent assortment?

Which of the following statements is a basic summary of one of Mendel's laws?

Suppose D were dominant and d were recessive,and you could label the D allele in the P generation with a radioactive substance that could be inherited over several generations.You create hybrids by mating your radioactive DD individuals to dd individuals.Finally,you cross two F1 individuals (with the Dd genotype).In 1,000 offspring,how many would you predict would be radioactive?

Mendel's manuscript discussing his pea-breeding results is considered one of the two most important scientific papers of the nineteenth century because he was the first to explain how

The figure shown illustrates

A thoroughbred racehorse could have at most ________ alleles of the same gene.
