Genetics Disorders
delusions-A belief or altered reality that is persistently held despite evidence or agreement to the contrary, generally in reference to a mental disorder.

Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
Genes
-
-
-
characteristics- A distinguishing quality, trait or feature of an individual, thing, disorder, etc.
-
Protien

Mutations
Delete mutation - is a mutation in which a part of a chromosome or a sequence of DNA is left out during DNA replication.
-
good mutation- a good mutation is a mutation that helps the organism survive, for example giving it an extra nostril so it can smell better.
bad mutation- a bad mutation could be a disease that lessons its survival skills by taking away it´s hearing or sight or comprehension
Variation- The difference in each organism's DNA, each organism's DNA is different that is reproduced sexually.
Natural selection- the process where organisms better adapt to their environment to survive there environment better and more successful.
Sexual Reproduction: (MALE and FEMALE) when a new organism is created from two parents, sperm from the male/dad and egg from the female/mom. Two advantages of sexual reproduction are one, it creates a genetic diversity between species, and Genetic variation can lead to evolutionary advancements. Two disadvantages of sexual reproduction are that ti can be deadly and fewer offspring are typically produced.
Asexual Reproduction: (ONE PARENT) offspring have almost identical DNA as parent. Two advantages of sexual reproduction are only one parent is needed, and it is faster than sexual reproduction. Two disadvantages are Negative mutations linger longer in asexual organisms, and There can be an inability to adapt.
Heredity
Alleles- one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
recessive-relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents
-
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
traits-The specific part of the gene, the outcome of the gene.For example blue eyes
