Two parents both have the following genotype: XXYYZZ X XXYYZZ What is the probability that they will have a child with this genotype: XXYYZZ Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer, 1/4 b 1/2

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%

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
