Is a branch of biology concerned with the study of genes, genetic variation and heredity in organisms.

Discovered the fundamental laws of inheritance

People started to understand the science of inheritance

This is also called Mendel's first law of inheritance

is a cross between two individuals that differ in two observed traits

HE CONDUCTED TWO EXPERIMENTS TO HIS LAWS MAIN CONCLUDE OF INHERITANCE

happens if individuals that crosses each other has only one different trait from each other

This is also called Mendel's first law of inheritance. According to the law of dominance, hybrid offspring will only inherit the dominant trait in the phenotype.

Also known as Mendel's second law of inheritance, the law of independent assortment states that a pair of traits segregates independently of another pair during gamete formation

states that during the production of gametes, two copies of each hereditary factor segregate so that offspring acquire one factor from each parent. In other words, allele (alternative form of the gene) pairs segregate during the formation of gamete and re-uniterandomly duringfertilization

the totality of non-genetic factors affecting the individual

refers to the specific combination of genes that are associated with a particular characteristic of the individual;

the observable manifestation of a given character of an individual;

One of two or more alternative forms of a gene which are usually recognizable by the phenotype

Gene may be active only when they occur in pairs of alleles during the diploid phase

control or regulate the function of other genes; may function in terms of quantity, quality or timing of the activity of certain structural genes

directly responsible for the synthesis of certain biochemical products during cell metabolism.

The corresponding trait determined by an allele which is manifested in the heterozygote form..

a pair of allelic genes contribute independently to the genotypic value; Ex. Inheritance of the roan coat color cattle.

allows the flow of the genetic material from generation to generation, involves two processes: gametogenesis and fertilization

taken from the Greek word which means "to stand upon". Interaction of between two or more genes so that one of them interferes with or even inhibits the phenotypic expression of the other gene

the process of cell, including meiosis; male produces sperm cells.

the process of producing the reproductive cells

mature reproductive cell capable of fusing with a similar cell of the opposite sex to form a zygote, also called sex cell.

the process of differentiation of a mature egg cell from an undifferentiatedgerm line cell, including meiosis; female produces eggs

the female gamete

male gametes of animals

a measure of the tendency of some genes to be inherited as a group rather than individually because of the proximity of their loci in the chromosome.

the fusion of two gametes of opposite sexes to form a zygote or an embryo.

carry genetic material but do not determine sex.

a place at which a particular gene resides on the genetic or linkage map.

genes that are located in the sex chromosomes.

determine the sex of the individual.

process in which certain genotypes contribute more progeny in the next generation than other genotypes.

The inheritance of certain characteristics that are associated with one sex or the other because the genes controlling them are located in the sex chromosomes.

a spontaneous change in the biochemical structure of the gene resulting in an entirely different phenotypic effect.

process in which individuals from one population transfer to another population.

individuals that are more phenotypically similar tend to mate often; tend to drive the population toward homozygosis

occurs when some individuals do not have the same chances of mating with individuals of the opposite sex.

Sex dimorphism in mammals

individuals which are less phenotypically similar tend to mate more other together than would be expected by chance; tend to maintain the production of more heterozygotes at the expense of homozygotes.

is an art and science of the genetic improvement of farm animals

individuals that are related by descent tend to mate more often than under random mating; also tend to drive the population towards the increase in the frequency of homozygotes

A form of non-random mating or a special case of assortative mating where individuals that ate related by ancestry are mated together.

Process in which some individuals are chosen over others parents of the next generation.

reduction in fitness or vigor because of inbreeding or normally cross-pollinate organisms.

an offspring of a cross between two genetically unlike individuals.

Mating animals that are more distantly related which can be traced back to one common ancestor.

Is the mating of two animals of different breeds.

The mating of males and females of the same breed or type
