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
