What is the probability that a mother with blood type O and a father with the genotype /Bi would have a child with blood type O? (Record your answer as a frequency between 0 and 1 rounded to two decimal places. Include the decimal) Answer:

If two Aa parents have four children then on average the predicted number of children with each genotype is AA____ Aa____ aa____

20)

Determine the probability of the following outcome if two individuals heterozygous for the a specific disease were to produce offspring with the assigned phenotype.  (6 offspring, 5 normal and 1 with disease.) Father and Mother are both heterozygous for the disease

For each genotype, indicate the phenotype: The freckles allele (F) is dominant to the no freckles allele ( f). The attached earlobes allele (E) is dominant to the unattached earlobes allele (e). ff _______________ Ee _______________ FF _______________ EE _______________ Ff _______________ ee _______________

Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)     0%     1/4 or 25%     2/4 or 50%     3/4 or 75%     4/4 or 100%

A female with genotype IBi has a child that has blood type O (genotype ii). Which of the following genotypes could the child's father have? Select all correct answers.   ii IAIB IAi IBIB

Answer the following: a. what environmental factors may increase incidence of chromosomal abnormalities? Name at least three. b. for a couple, what is the significance of knowing chromosomal aberrations?

Use the given terms (in parentheses) to complete the following sentences. (closed square, controlled mating, diamond, hexagon, open circle, open square, pedigree, two horizontal bars) Due to the limitations of studying humans investigations rely on pedigree analysis. The symbol used in a pedigree for an affected male is a closed square. The symbol for an unaffected female is an open circle. An individual of indeterminate sex is represented by a diamond in a pedigree. In a pedigree a consanguineous mating is diagrammed as_______between a male and a female.

Blood type is determined by multiple codominant alleles of the I gene, IA, IB, and i, where ii results in type O. The genotypes of a husband and wife are IAIB x IAi. Among the blood types of their children, how many different genotypes and phenotypes are possible? Group of answer choices 2 genotypes, 3 phenotypes 4 genotypes, 3 phenotypes 3 genotypes, 3 phenotypes 3 genotypes, 4 phenotypes
