The potential concerns with genetic engineering can be some ethical concerns, decrease genetic diversity, and not understanding the full effects of altering DNA. The correct options are 1, 3, and 4.
<h3>What is genetic engineering?</h3>
Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.
This could entail changing a single base pair (A-T or C-G), deleting a region of DNA, or inserting a new segment of DNA.
The potential concerns with genetic engineering can be some ethical concerns, decrease genetic diversity, and not understanding the full effects of altering DNA.
Thus, the correct options are 1, 3, and 4.

During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell. Mitosis has the following phases: prophase, metaphase, anaphase and telophase.
If there is a 25% chance of white with short hair, white with long hair, black with short hair, and black with long hair, then there should be a 50% chance since there is a 25% chance each of 2 different short hair bunnies. Hope this helps!
Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
