Q: Answer the following question given this paragraph: A pedigree is a chart which shows the inheritance of a trait over several generations. A pedigree is commonly created for families, as it can be used to outlines the inheritance patterns of familial traits or genetic disorders. It can be used to demonstrate autosomal dominant or recessive inheritance, or sex-linked inheritance. Figure below shows a pedigree depicting recessive inheritance of a disorder through three generations. The trait is thought to be recessive as for the two individuals with the trait, neither has a parent who also has the trait. Geneticists may also be able to determine whether individuals with the trait in question are heterozygous or homozygous for the allele associated with the trait. When alleles are added to the pedigree shown ( A or a ), recessive inheritance in conformed. Q: A pedigree is a chart which shows the inheritance of a trait over several what? Choices: - centuries - events - organisms - generations A:
A: generations

Answer the following question given this paragraph: During a nuclear decay process that occurs by positron emission, a proton is converted into a neutron and a positron. The neutron remains in the nucleus, and the positron is expelled. Overall, the atomic number of the parent nucleus increases by one, and the mass number is unchanged. For example, carbon-11 emits a positron to become boron-11:. Q: What happens to the mass number during a nuclear decay process by positron emission? Choices: - it rises - it decreases - it increases - remains unchanged A:
**Answer**
remains unchanged
