Exam 10: Patterns of Inheritance

Phenotype means:

The movement of DNA from one chromosome to a nonhomologous chromosome that will be passed onto future generations:

Autosomes:

If a pea plant is heterozygous for yellow seeds (Yy),which gametes could it produce?

If you cross two pea plants,one with green peas and the other with yellow peas.All of the offspring have yellow peas.The yellow and green parental plants:

Organisms other than humans have mechanisms other than the X and Y chromosomes for determining sex of an individual.

In humans,alleles are inherited from:

X-linked recessive disorders affect more females than males.

In a karyotype,the major characteristics that uniquely identify each chromosome are:

What did the researchers conclude from figure 10.28?

If a person has a recessive allele for a disease and that allele is masked by a normal dominant allele,this person:

Genotypes are the outward expression of an allele combination.

If while examining a human karyotype,it is observed that there are 22 paired chromosomes and two chromosomes that are not the same size,this would most likely be due to:

Having the alleles Tt is:

When scientists inserted the Bt toxin gene into plant cells they created a _____.

In an inherited form of high cholesterol,rr individuals have a blood cholesterol level greater than 500mg/dL,Rr individuals are near 300mg/dL,while normal (RR)cholesterol levels should be less than 200mg/dL.The R allele is ___ to the r allele.

A male expresses an X-linked recessive disorder only if he inherits these alleles from both parents.

If the two alleles for a particular gene are identical the gene pair is:

A dihybrid cross of linked genes theoretically gives a phenotypic ratio of:

A gene that produces a protein that is important in more than one biochemical pathway is a ___ gene.
