- Q1What is the correct definition of heredity?The passage of genetic instructions from one generation to the next generationThe impact of environment on genetic traitsThe process of creating offspringThe study of family trees30s7.14a
- Q2Which type of reproduction results in genetically diverse offspring?BuddingSexual reproductionBinary fissionAsexual reproduction30s7.14b
- Q3Why does sexual reproduction usually result in a high genetic diversity compared to asexual reproduction?Because it involves a single parentBecause the offspring inherits traits from grandparentsBecause it induces mutations during reproductionBecause it involves the blending of genes from two different parents30s7.14b
- Q4Which type of reproduction, sexual or asexual, is more likely to improve a species' ability to adapt to environmental changes?Neither improve a species' adaptabilitySexual reproductionAsexual reproductionBoth are equally likely30s7.14b
- Q5What is the main advantage of sexual reproduction over asexual reproduction?Less energy requiredIncreased genetic diversityNo need for a mateFaster reproduction rate30s7.14b
- Q6Which reproduction method, sexual or asexual, results in offspring genetically identical to the parent?NeitherBothAsexual reproductionSexual reproduction30s7.14b
- Q7What is a potential disadvantage of asexual reproduction compared to sexual reproduction?Requires two parentsLeads to fewer offspringMore time consumingLess genetic variety among offspring30s7.14b
- Q8Certain species of yeast can reproduce sexually or asexually. Which answer choice best compares the offspring from sexual reproduction to the offspring from asexual reproduction?offspring of sexual reproduction have twice as much genetic material as the offspring of asexual reproductionoffspring of sexual reproduction are larger than the offspring of asexual reproductionoffspring of sexual reproduction are genetically different from either parent and offspring of asexual reproduction are identical to the parentoffspring of asexual reproduction are genetically different from each other and offspring of sexual reproduction are identical to the parent30s
- Q9A litter of puppies was just born. Even though the puppies have the same parents, they do not all look alike because -they were produced by asexual cloningsome of the puppies have genetic material from only one of the parentsall the puppies developed from the same fertilized eggeach puppy has a different combination of genetic material as a result of sexual reproduction30s
- Q10The hydra is a very small, simple animal that live in water. Hydras reproduce asexually by budding, a process in which a bud breaks off an adult hydra and floats away. Which of the following describes a hydra bud?a hydra bud has half as much genetic material as the parent hydraa hydra bud has different mutations than the parent hydraa hydra bud contains genetic material from its two parentsa hydra bud is genetically identical to the parent hydra30s
- Q11Gregor Mendel studies the genetics of pea plants. He found that some pea plants produce smooth, round seeds, while other pea plants produce rough, wrinkled seeds. Which cellular feature determines whether a pea plant produces smooth or wrinkled seeds?chemical signals released by mitochondriainformation found in proteins of the cytoplasminformation present in chromosomes in the nucleusinformation located in the plasma membrane30s
- Q12A tiger cub has a pattern of stripes on its fur that is similar to that of its parents. Where are the instructions stored that provide information for a tigers fur pattern?in cytoplasm inside cellson genes within chromosomeson the cell membranein the mitochondria30s
- Q13Which organelle stores the information that determines an individual's blood type?243130s
- Q14The cousins shown have a similar appearance but different face shapes. Which of these cell components are most involved in determining the basic shape of each girls face?vacuoles, nucleus, and chromosomeschromosomes, chloroplasts, and vacuolescytoplasm, chloroplasts, and genesgenes, chromosomes, and nucleus30s
