QuestionAnswer
A type of reproduction in which offspring arise from a single organism and inherit the genetic material of that parent only.Asexual Reproduction
What environments are advantageous for asexual reproduction?Asexual reproduction has advantages in stable environments.
In asexual reproduction, only one parent organism is required to produce offspring.Single Parent
How many parents are needed for asexual reproduction?Only one parent is needed for asexual reproduction.
A benefit of asexual reproduction where offspring can be produced more rapidly compared to sexual reproduction.Faster Offspring Production
How does asexual reproduction contribute to faster offspring production?Offspring can be produced faster than in sexual reproduction.
A characteristic of asexual reproduction where numerous offspring are genetically identical to the parent organism.Many Identical Offspring
What advantage does asexual reproduction offer when conditions are favourable?Many identical offspring can be produced when conditions are favourable.
An environment characterized by consistent conditions that do not change significantly over time.Stable Environment
What type of environment is advantageous for asexual reproduction?A stable environment is usually an environment that doesn't change much.
The absence of genetic diversity among offspring produced through asexual reproduction, as they are genetically identical to their parent.Lack of Variation
What is a drawback of asexual reproduction in terms of genetic variation?Asexual offspring are identical to their parents and to each other, resulting in no variation in the population.
The susceptibility of a population to negative impacts from environmental changes due to lack of genetic diversity.Vulnerability to Changes
What risk do asexual organisms face in changing environments?They will all be vulnerable to the same things due to lack of genetic variation.
The susceptibility of a population to diseases due to genetic uniformity, common in asexual reproduction.Disease Vulnerability
How can lack of genetic variation in asexual populations lead to vulnerability to diseases?If a new disease emerges, all offspring may be vulnerable to that disease.
Offspring from sexual reproduction are more likely to survive changing environments.Survival in Changing Environments
What advantage do offspring from sexual reproduction have in changing environments?Offspring from sexual reproduction are more likely to survive changing environments.
The presence of different characteristics among offspring produced through sexual reproduction.Variation in Offspring
What is meant by variation in the offspring of sexual reproduction?Variation means that the offspring have different characteristics.
A benefit of variation in offspring where some individuals are more likely to survive environmental changes.Increased Survival
How does variation in offspring contribute to their survival in changing environments?Variation means that some offspring are more likely to survive if the environment changes.
Inherited resistance to a particular disease or pathogen.Natural Immunity
What advantage do some offspring from sexual reproduction have if a new disease emerges?Some offspring may have natural immunity to that disease.
The transmission of inherited traits or characteristics from one generation to the next.Passing on Characteristics
What happens when offspring with immunity to a disease survive and reproduce?They pass on their immunity to the next generation.
The likelihood of offspring without immunity to a disease dying out in changing environments.Decreased Survival
What is the fate of offspring that don't have immunity to a disease in changing environments?Offspring without immunity are more likely to die out.
Reproduction involving the fusion of a male gamete with a female gamete to produce offspring.Sexual Reproduction
What happens in sexual reproduction?In sexual reproduction, a male gamete fuses with a female gamete.
A special type of cell division that produces gametes with half the number of chromosomes as the parent cell.Meiosis
How are gametes formed?Gametes are formed through a special type of cell division called meiosis.
The cells resulting from cell division; in meiosis, each division produces four daughter cells.Daughter Cells
What is produced during each meiotic cell division?Each meiotic cell division produces 4 daughter cells (the gametes).
Cells that contain half the normal number of chromosomes, characteristic of gametes.Haploid Cells
What are cells with only half of the normal number of chromosomes called?Cells with only half of the normal number of chromosomes are known as haploid cells; gametes are haploid cells.
The specific combination of genes an organism possesses.Genetic Make-up
Are haploid daughter cells identical?No, these haploid daughter cells are not the same; each has a different genetic make-up.
The combination of genetic material from two gametes during fertilization.Genetic Information Mixing
What happens when male and female gametes fuse?When the male and female gametes fuse, their genetic information mixes.
Differences among offspring resulting from the mixing of genetic information during sexual reproduction.Variation in Offspring
What does the mixing of genetic information in sexual reproduction lead to in offspring?This mixing leads to variation in the offspring produced, so all the offspring are different.
