(a)
To determine: The probability of different probable genotypes in offspring if the man and his wife both are carriers of the recessive allele causing phenylketonuria (PKU).
Concept introduction: During gamete formation, two alleles of a gene segregate into different gametes. This is based on the Mendel’s law of segregation. After the genetic cross, the allele combinations are predicted that determine the genotype of the offspring. The occurrence of genotypes can be determined on the basis of probability rules.
(b)
To evaluate: The probability of one or more of the three children having disease.
Concept introduction: During gamete formation, two alleles of a gene segregate into different gametes. This is based on Mendel’s law of segregation. After the genetic cross, the allele combinations are predicted which determine the genotype of the offspring. The occurrence of genotypes can be determined on the basis of probability rules.
(c)
To evaluate: The probability of all three children having disease.
Concept introduction: During gamete formation, two alleles of a gene segregate into different gametes. This is based on Mendel’s law of segregation. After the genetic cross, the allele combinations are predicted which determine the genotype of the offspring. The occurrence of genotypes can be determined on the basis of probability rules.
(d)
To evaluate: The probability of one child having a normal phenotype.
Concept introduction: During gamete formation, two alleles of a gene segregate into different gametes. This is based on Mendel’s law of segregation. After the genetic cross, the allele combinations are predicted which determine the genotype of the offspring. The occurrence of genotypes can be determined on the basis of probability rules.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
