Assuming that 50% of the offspring are male and 50% are female, what is the probability of this couple having a daughter with long index fingers?

In humans, an individual who is XXY would be

The binomial expansion equation is used to solve problems in which

Two genes are 18 map units apart. In a testcross, what percentage of offspring is expected to be recombinants?

For genes which have multiple alleles, the relationships between those alleles can be a variety of types of dominant/recessive relationships.  

The end result of mitosis in animals is ________.

In a chi square analysis involving genes that may be linked, which of the following statements is false?

Let’s consider two different traits in mice. A two-factor cross was made involving true-breeding mice with stubby tails and white fur to wild-type mice with long tails and black fur. All F1 offspring had long tails and black fur. The F1 offspring were then crossed to mice with stubby tails and white fur. Which of the following are the F2 recombinant offspring?

True-breeding plants with yellow/round seeds were crossed to true-breeding plants with green/wrinkled seeds. All of the F1 plants produced yellow/round seeds. The genes that affect these traits independently assort. If the F1 plants were crossed to plants that produce green/wrinkled seeds, the ratio of seed phenotypes of the F2 generation would be 

A misaligned crossover between homologous chromosomes will produce two chromosomes in which
