Explanation of Solution

(a)

Correct answer: Alleles

Explanation: Genes have alternate forms known as alleles. The two alleles of a gene segregate into different gametes and are transmitted to offspring. Hence, the correct answer is alleles.

(b)

Correct answer: Loci

Explanation: Genes are DNA sequences that code for specific traits. The specific position of a gene on a chromosome is known as locus. The plural of locus is loci. Hence, the correct answer is loci.

(c)

Correct answer: Homozygous

Explanation: The alleles of a gene segregate into gametes and transmitted to offspring. They are dominant and recessive alleles. When the two alleles are same in an individual(either dominant or recessive), its genotype is homozygous. Hence, the correct answer is homozygous.

(d)

Correct answer: Dominant

Explanation: Dominance in alleles of a gene occurs when a phenotypic effect of one allele suppresses the phenotypic effect of a second allele. If the two alleles are different in an individual, then the dominant allele out of the two alleles expresses itself and determines the phenotype. Hence, the correct answer is dominant.

(e)

Correct answer: Recessive

Explanation: A dominant allele masks the expression of a second allele. The masked allele is known as recessive because its phenotypic effect is suppressed. Hence, the correct answer is recessive.

(f)

Correct answer: Incomplete dominance

Explanation: Dominance explains how different alleles of a gene express themselves. Some genes show incomplete dominance, which means that individuals with homozygous alleles produce offspring that is intermediate of the two parent alleles. Hence, the correct answer is incomplete dominance.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
