Humans have been manipulating the genes of organisms for thousands of years through selective breeding and agricultural practices. This began with the domestication of plants and animals around 10,000 years ago. More recent advancements, particularly in the 20th century with the development of genetic engineering techniques, have allowed for more precise manipulation of genetic material. Today, biotechnology enables significant modifications at the molecular level, expanding the scope and speed of genetic manipulation.
Even though yeasts are single-celled organisms and humans are not they do share genes that would show they have a common ancestry. Some of the housekeeping genes are the same in yeasts and in humans. One of those housekeeping genes that enables energy to be obtained from the breakdown of sugars.
True. When human genes are inserted into bacteria and produce proteins, it demonstrates that genetic material from humans has been introduced into another organism, making the bacteria transgenic.

Gene splicing has been done since the 1970s when scientists developed the technique for manipulating DNA. Through gene splicing, specific genes can be inserted, deleted, or modified in an organism's genome. This technology has revolutionized fields such as genetic engineering and biotechnology.
If different organisms have similar genes, it often indicates a shared evolutionary ancestry, suggesting that they diverged from a common ancestor at some point in their evolutionary history. This genetic similarity can also reflect conserved functions essential for survival, as these genes may perform critical biological roles. Additionally, it may highlight evolutionary adaptations that have been retained across species due to their advantages in specific environments. Overall, such genetic similarities provide insight into evolutionary relationships and the mechanisms of evolution.

Both worms and humans share a common ancestor, and many essential genes have been conserved throughout evolution to carry out basic biological functions. Despite the differences in complexity and morphology between worms and humans, many genes are required for common processes such as development, metabolism, and cellular functions. Therefore, a similar number of genes are necessary to ensure the survival and function of both organisms.
A plant that contains a gene or genes from another organism that has been introduced artificially into the plant's genetic makeup is called a transgenetic plant. It is also called genetic engineering.
A domesticated population refers to organisms that have been bred and raised by humans for various purposes such as food, work, or companionship. These organisms often rely on humans for their care and survival.
Humans share at least some genes (DNA) with all living organisms. As far as plants, it is around 15%.

Yes, it has been proven that chickens are related to raptors. They are genetically more related to raptors than T-Rex is. Scientists are currently working on manipulating the genes of a chicken to make a raptor.
Transgenic animals are animals that have had genes from other organisms inserted into their DNA. This can occur naturally or be done artificially in a lab. The term transgenic organisms usually refers to those which have been modified artificially by humans.
Different animals have different numbers of genes (and chromosomes). The exact number of genes that animals have has not been proven for many species, so estimates have been made. It is estimated that humans and mice have approximately 20,000 genes, roundworms have approximately 13,000 genes and yeast has around 6,000 genes. It should be noted that, similar to chromosome number, a larger number of genes does not necessarily mean the organism is more complex - for example rice has over 46,000 genes.
To my knowledge, the crow genome has not been sufficiently analyzed for a definite answer. The process of complete genome analysis is time consuming and expensive, so scientists have been selecting organisms that are highly used in research for genome analysis. That said, the genome of the chicken has been mostly completed. Given that chickens aren't that much closer to or further from humans than crows, the DNA similarity between humans and chickens is at least in the same ballpark as humans and crows. The chicken genome is about 1/3 the size of the human genome (1.2Gb instead of 3.4 Gb) but this is not due to much to birds having fewer genes as having mostly the same genes more compactly arranged in chromosomes. My own experience (I have a little experience with chicken genetics) has been that chicken genes tend to be about 75-85% identical with human genes.
A transgenic organism is an organism that has been genetically engineered. It has genes from more than one organism. Can be both, male or female.
