When a direct-to-consumer genetic testing companies performs Late-Onset Alzheimer’s genetic testing they perform [1], to determine your [2] for Alzheimer’s. However, studies have found that testing companies use different tests and calculations to determine your results, and can produce false positives. Accurate and reliable test results are important and are described as [3], while whether these results are of significance in the disease is referred to as [4]. 

Is there any way for a biological female with type A blood and a biological male with type B blood to have: a child with type O blood? [yes1] a child type type A blood? [yes2] a child with type B blood? [yes3] a child with type AB blood? [yes]

A yeast strain was exposed to a chemical mutagen. As expected, exposure to mutagen resulted in a DNA sequence change in an essential gene (required for survival) you examined. Yet this mutation did not result in any lethal phenotype (cause death). Which of the following answers would BEST explain this apparent discrepancy?

Choose the best answer from the choices below. A couple has a child with cystic fibrosis. Neither parent has cystic fibrosis. This couple wants to have a second child. What is the probability that this second child will have cystic fibrosis?

The 2023 Guardian article discusses the positive impacts of delaying fatherhood on children’s health, with older fathers contributing 1-2 fewer SNPs/year than younger fathers.   

Which of the following is NOT true regarding how genetic variants/mutations occur and result in genetic diseases and disorders?

The end result of meiosis is:

Iceland is a genetic goldmine because the population is very large and diverse, therefore providing a lot of diversity in genomic data. 

The recent cloning of two endangered black-footed ferrets marks the third successful cloning of black-footed ferrets from frozen tissue. 

In Mendel’s experiments, a pea was either yellow or green, and the yellow trait was dominant over the green trait. If a pea plant with yellow peas (P0) is crossed to a pea plant with green peas (P0) and 42 offspring have yellow peas and 13 have green peas, what is the genotype of the parent plant (P0) with yellow peas? [Yy]   If a pea plant with yellow peas (P0) is crossed to a pea plant with green peas (P0) and all the offspring have yellow peas, what is the genotype of the parent plant (P0) with yellow peas? [YY]
