Answer/Explanation:
Mendel could have crossed a true breeding (homozygous) brown fly with a true breeding (homozygous) black fly. BBx bb. The resulting offspring would all be Bb (heterozygous). If brown body color is dominant to black body color, all of these heterozygous flies would always be brown. This is because the brown allele is displayed over the black allele.
Answer:
mutations can be either beneficial or harmful depending on the environment
Explanation:
Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.
First thing to remember is that interphase is a stage associated with replication of DNA, and growth.
Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth.
True that should be the answer
