the most common phenotype in a natural population is referred to as thewild type
incomplete dominance is a condition in plants and people whereoffspring have an appearance in between the phenotypes of the two parents
An important technique that helps provide insight into interesting genetic questions at the molecular level, such as reasons for hairless dogs, is called _____.dna sequencing
The ABO blood group in humans is an example of __________ producing four phenotypes.multiple alleles
Which of the following is used to define a phenotypic characteristic resulting from the expression of two or more genes?polygenic inheritance
A plant with the genotype AABbcc is __________.homozygous for two different genes
Linked genes are genes that __________.are on the same chromosome
The physical traits of an organism are called its _____.phenotype
A gene that is located on a sex chromosome (X or Y chromosome) is __________.a sex-linked gene
This genetic disorder causes red blood cells to assume an unusual shape and produce abnormal hemoglobin proteins.sickle cell disease
Why are human males much more likely than human females to inherit the recessive condition hemophilia (a failure of the blood to clot properly)?the gene for hemophilia is sex-linked
You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered snapdragon. All of the F1 are pink. What can you say about the alleles for the parental traits?Red and white show incomplete dominance.
The sex chromosomes in humans that make an individual a male are _____.X and Y
Which of the following is a true statement?A testcross is a mating between an individual with a dominant phenotype (but unknown genotype) and a homozygous recessive individual.
Which of the following statements is correct?Offspring of two different true-breeding varieties are called hybrids.
In humans, the __________ determines the sex of the offspring because __________.male ... the male can contribute either an X or a Y chromosome
In a dihybrid cross ratio, what is the probability of getting the genotype aa when you cross genotypes Aa and aa?1/2
The scientific study of heredity is called _____.genetics
GgTt pea plants can produce _____ type(s) of gamete(s), but a ggtt plant can produce _____ type(s) of gamete(s).four ... one
Assume you were studying two characteristics of peas, and when you crossed heterozygous F1 individuals you did not see the 9:3:3:1 ratio predicted for a dihybrid cross. You later found that these two characteristics were on the same chromosome. With this information, how would you explain the results?The genes are linked and are inherited together.
