Genetics

Genetic terms, the role of G+E on the P expression, gene action, the mechanics of inheritance, the Mendelian inheritance, genes in population.

Objectives of animal breeding, systems of breeding, inbreeding and crossbreeding.

Reproduction and rate of genetic improvement, animal reproductive biotechnologies

A branch of biology that deals with heredity and variations of organisms.

Transmission of traits from generation to the next generation.

Deals with the genetic differences between organisms

Deals with the transmission of genes from generation to generation.

Study of heredity in groups of individuals.

Three main areas in Animal Genetics

Smallest unit of inheritance, found as segments of DNA on a chromosome.

Play a central role in determining various traits and characteristics of an organism, including its physical appearance, physiological processes, and susceptibility to diseases.

Store and transmit genetic information from cell to cell and from parent to offspring.

Copy or replicate itself with great consistency and precision

Undergo mutation or error in copying which would subsequently copied and replicated.

Cound in the nucleus of the cell, and forms the backbone of chromosome.

In Deoxyribonucleic acid (DNA) the spiral or double helix structure composed of ?

DNA itself is wound up into a thin fiber which is wrapped around proteins called?

The histones and DNA structure forms a beadlike structure known as?

Slender, thread-like strands that contain the units of inheritance (genes).

How many sister chromatids?

It is made of protein and a single molecule of DNA (chromatin).

Genes occupying corresponding loci on homologous chromosomes that affect the same trait but in a different way.

Genes on the same locus controlling a trait in the same way are called “homozygous”, and if they contrast in controlling the trait, they are called “heterozygous”.

Specific location of a gene on a chromosome.
