Homozygous refers to having the same or identical alleles for a single trait.
So, your answer is YY or yy
Hope this helps :)
Explanation:
Cancer cells do not contain the capacity to undergo
- a regular cell cycle where they only undergo cell division in response to external signals within their environment, i.e. regulation.
- differentiation into specialized cell types, with different physical traits; together they can't form different tissues.
Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer.
Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.
Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Is there anything to choose from it would make this easier to answer and also growth hormones are bad for animals and now im just chattering, the chatting chatter-box i like the sound of that the clouds are nice and fluffy today like cotton candy im bored im supposed to be doing my homework but i dont like writing i mean why have to write when your home schooled i like anime and manga this thing that i go on has a story called nobless its really good and also snailogy by snail lords he is awesome he is a hermaphrodite but he likes being called a boy instead oh yeah im supposed to be answering this sorry but i forgot have a good day here are some things that you could enjoy instead (0^0) (/O.O)/ |__| (o___-) (o_____o)
Often a plasmid is used in recombinant cloning technology to clone newly isolated genes. It is also very common to use a recombinant plasmid to express large amounts of a known gene to obtain RNA or protein from it. Such recombinant gene expression has been indispensable for the biotechnology industry.
