Question:
DNA
Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. ... The information in DNA is stored as a code made up of four chemical
bases: adenine (A), guanine (G), cytosine (C), and thymine (T). NA contains
the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies
Question:
Genes
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are 1 / 4
made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins
Question:
Chromosomes
Answer:
The chromosomes of a cell are in the cell nucleus. They carry the genetic information. Chromosomes are made up of DNA and protein combined as chromatin. Each chromosome contains many genes. Chromosomes come in
pairs: one set from the mother; the other set from the father.
Question:
Mitosis vs. Meiosis
Answer:
Mitosis and meiosis are nuclear division processes that occur during cell division. Mitosis involves the division of body cells, while meiosis involves the division of sex cells
Question:
Genotype
Answer:
The genotype is the part of the genetic makeup of a cell, and therefore of any individual, which determines one of its characteristics (phenotype). 2 / 4
Question:
Phenotype
Answer:
Phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Question:
Dominance
Answer:
the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive.
Question:
Recessive gene
Answer:
recessive gene is a gene that can be masked by a dominant gene. In order to have a trait that is expressed by a recessive gene, such as blue eyes, you must get the gene for blue eyes from both of your parents. You might remember the word recessive from biology, where it most often appears.

Question:
Sex Linkage
Answer:
Sex linkage is the phenotypic expression of an allele that is dependent on the gender of the individual and is directly tied to the sex chromosomes. In such cases there is a homogametic sex and a heterogametic sex.
Question:
Cloning
Answer:
Cloning is the process of taking genetic information from one living thing and creating identical copies of it. The copied material is called a clone.Geneticists have cloned cells, tissues, genes and entire animals
Question:
artificial insemination
Answer:
Artificial insemination (AI) is the deliberate introduction of sperm into a female's cervix or uterine cavity for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse.
