What is the difference between natural selection and artificial selection?

Biology

sweet [91]3 years ago
8 0

Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.

Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.

Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits.

Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.

What chromosomes are found in body cells but not sex cells?
Leni [432]
None, egg cells don't have chromosomes. No, sex cells do have chromosomes. meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

With incomplete dominance a likely ratio of phenotypes in the F2 generation resulting from a monohybrid cross between two true-b
nydimaria [60]

Answer:

A) 1:2:1

Explanation:

Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles.  Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.

In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.

Thus, Option-A is the correct answer

Explain the different levels of cellular organization.
JulijaS [17]

There are 5 different levels of cellular organization.

Cells, tissues, organs, organ systems and whole organisms. Cells hold genetic material and absorb outside energy.

Tissues make up the bones, nerves and connective fibers of the body. Organs work to perform specific bodily tasks, such as filtering blood. Organ systems are groups of organs that perform a specific kind of function together, such as digesting food.

Together, these smaller systems make up an entire living organism which can grow and then go onto reproduce.
