Animal Science chapter 6

Punnett square

A technique for predicting genotype

Distinguish between dominant and recessive

Dominant - trait that mask recessive trait Recessive- trait that can be masked by dominant trait

What is genetic engineering?

The deliberate modification of the characteristics of an organism by manipulating its genetic material

Chromosome

Threadlike parts of a cell that contains genetic material

biotechnology

Using biological systems for the benefit of humans

Synthetic bio

Using chemicals to create systems with the characteristics of living things

Transgenic animal

An animal that has a foreign gene in its cell

DNA

A molecule that controls inheritance

What is recombinant DNA? how can recombinant DNA technology used?

DNA from different organisms, making drugs and better products

how is the genetic code related to recombinant DNA

Find sequences to put into DNA

What is genetics? why is genetics important to understanding biotechnology?

Genetics are a segment of a chromosomes that contains hereditary traits

Distinguish between genotype and phenotype

Genotype- genetic make up Phenotype- what a trait looks like ( Tall, short)

Distinguish between heterozygous and homozygous

Heterozygous- alleles are different (Tt) Homozygous - alleles are the same (TT)

Distinguish between the two main types of biotechnology

Molecular Biotechnology- changes the physical appearance Organismic- deals with intact or complete organisms, improving organisms with out artificially altering their genetic make up

What are mutations? how are mutations helpful

Mutation is a change that naturally occurs in genetic material of an organism, they can improve animal production

Mutation

changes that occur naturally in the genetic material of an organism

Molecular biotechnology

changing the structure and parts of a cell to change an organism

Describe the relationship between DNA, genes and chromosomes

chromosomes are made of genes, that are made of of DNA

Gene

the part of a chromosomes that contains hereditary material

phenotype

the physical features or appearances of an animal
