What are desired characteristics of an organism determined by?

What are desired characteristics of an organism determined by?

A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.

How do you do selective breeding?

Main steps involved

1. decide which characteristics are important enough to select.
2. choose parents that show these characteristics.
3. choose the best offspring from parents to produce the next generation.
4. repeat the process continuously.

Can human beings produce desired characters in their offspring?

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

How do genes transfer from parent to offspring?

One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.

How is science using selective breeding to better society?

Selective breeding leads to future generations of selectively bred plants and animals, all sharing very similar alleles which will reduce variation. Inbreeding can lead to a reduced range of alleles in the gene pool, making it more difficult to produce new varieties in the future.

Which of the following is the process of choosing parent organisms for the characteristics that is wanted in their offspring?

Selective breeding involves selecting parents that have characteristics of interest in the hope that their offspring inherit those desirable characteristics.

How does selective breeding provide evidence for evolution?

Selective breeding of domesticated animals shows that artificial selection can cause evolution. Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function. Populations of a species can gradually diverge into separate species by evolution.

How are plants and animals developed through selective breeding?

Different varieties of plants and animals with desired characteristics can be developed by selective breeding. Selective breeding is the traditional method for improving crops and livestock, such as increasing disease resistance or milk yield. Natural selection and selective breeding can both cause changes in animals and plants.

What should you consider when choosing an experimental organism?

Safety is another important consideration in choosing an experimental organism. What harm you or the environment? people sick. The organism should grow vigorously in the lab environment, but should not be able to survive outside the laboratory. The organism should not be able to infect plants or animals.

How to describe the characteristics of living organisms?

list and describe the characteristics of organisms define the terms nutrition, excretion, respiration, sensitivity, reproduction,growth and movement outline the use of a hierarchical classification system for living organisms classify living organisms into kingdoms, orders, classes, families, generaand species

How is growth seen in all living things?

Growth is seen in all living things. It involves using food to produce new cells.The permanent increase in cell number and size is called growth. 6 Reproduction All living organisms have the ability to produce offspring. 7 Sensitivity All living things are able to sense and respond to stimuli around
