MB ASCP Study Questions (1) & Answers 2024 Which of the following terms refers to the proportion of individuals affected by an autosomal dominant condition that displays manifestations? A. codominance B. penetrance C. expressivity D. influence E. passivity - ANSWER-Answer Key: B penetrance Feedback: Certain autosomal dominant conditions are variably expressed due to differences in penetrance and expressivity. Penetrance refers to how people with the genetic abnormality manifest dise...

Sex Chromosome - ANSWER CHROMOSOME that determines the SEX of the individual Alleles - ANSWER One of a number of ALTERNATIVE VERSIONS of a gene posessing a UNIQUE nuceotide sequence. These come from mutations. 2 IDENTICAL alleles = HOMOzygous; 2 DIFFERENT alleles = HETEROzygous. Genotype - ANSWER The GENETIC MAKEUP of an individual. It is a COMPLETE set of alleles, the genes found in a person's DNA, and has profound inf...

Adaptation- - The adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. Aerobic- - A process that requires oxygen. Allele -An alternative form of a gene. An example would be genes that encode eye color—some encode blue eyes (one allele), while others encode brown, green, or hazel eye colors (other alleles). - amino acids - - A small organic molecule with the structure of an amino group, a carboxylic acid group, and an "R...

Homozygous correct answer: Having two identical alleles for a trait Heterozygous correct answer: Having two different alleles for a trait Allele correct answer: the different forms of a gene. Dominant allele correct answer: an allele whose trait always shows up in the organism when the allele is present Recessive allele correct answer: an allele that is masked when a dominant allele is present Codominance correct answer: situation in which both alleles of a gene contribute t...
