lesson 13 unit 4 A

Little genetic variation would occur within a population of animals and plants that is widespread over an area with a great range of different environmental conditions.

False

Science has documented mechanisms by the scientific method, by which new genes can be acquired during reproduction.

False

The genetic information in a gamete is identical to one of the original separated sets of chromosomes in the parent.

False

All variations within organisms can be explained by the known principles of genetics.

True

Some plants and animals can reproduce both asexually and sexually.

True

Successful breeding is limited to the gametes of the same created "kinds" of organisms.

True

The ability of an organism to to its environment is due to potential variation.

adapt

Variation produced by sexual reproduction starts:

during meiosis

When gametes fuse or come together to make one cell, has occurred.

fertilization

The genetic requirement for evolution to operate is the acquiring of new during reproduction.

genetic information

Adaptation is possible due to the known mechanism of:

genetic recombination

The most significant characteristic of sexual reproduction is:

genetic variability

A species may successfully live in its environment due to .

genetic variation

The method by which new genes can be acquired by successive generations:

has been imagined as evolution theory has never been documented by the scientific method

Why is sexual reproduction associated with meiosis?

meiosis produces gametes meiosis helps to generate variability

Variations of traits within a population are the result of genetic recombination of genes.

pre-existing

The haploid chromosomes of a gamete are formed by of the chromosomes of the parent cell, after the phase of division.

recombination first

The fusing together of two gametes at fertilization is called reproduction.

sexual

Three advantages of sexual reproduction are: genetic , resistance to unfavorable conditions, and produces disease free seed plants.

variations

Which statements correspond correctly to sexual reproduction?

variations remain within created kinds all genetic information comes from preexisting genes
