In honeybees, drones arise from _____ eggs, and workers arise from _____ eggs.- diploid; fertilized haploid
- unfertilized haploid; diploid
- unfertilized haploid; fertilized haploid
- fertilized haploid; unfertilized haploid - (correct answer)unfertilized haploid, fertilized
haploid
Reproduction in which offspring receive genetic material from two parents is called
- asexual reproduction.
- parthenogenesis.
- vegetative reproduction.
- sexual reproduction.
- binary fission. - (correct answer)Sexual reproduction
In sexual reproduction, meiosis produces _____ cells from one parent that join with
_____ cells from the other parent to form a _____ zygote.
- haploid; diploid; diploid
- haploid; haploid; diploid
- diploid; diploid; haploid
- haploid; diploid; haploid
- diploid; diploid; diploid - (correct answer)Haploid; haploid; diploid
What process produces gametes for sexual reproduction?
- mitosis
- binary fission
- clonal duplication
- meiosis
,- parthenogenesis - (correct answer)Meiosis
Production of offspring from the nonsexual tissues of a parent is called
- mitosis.
- binary fission.
- clonal duplication.
- vegetative reproduction.
- parthenogenesis. - (correct answer)Vegetative reproduction
Clones are offspring produced _____ and have the same _____ as the parent.
- sexually; phenotype
- sexually; genotype
- asexually; phenotype
- asexually; genotype - (correct answer)Asexually; genotype
Asexual reproduction
- occurs when offspring are produced by two parents without copulation.
- occurs when offspring are produced by and receive genetic material from only one
parent.
- occurs when offspring are produced by and receive genetic material from both
parents.
- is accomplished only via parthenogenesis.
- is accomplished only via vegetative reproduction. - (correct answer)occurs when
offspring are produced by and receive genetic material from only one parent.
Parthenogenesis occurs when offspring are produced
- from a parent's gonad tissue.
- by a cell dividing into two identical cells.
, - from an unfertilized embryo.
- from a parent's nonsexual tissue.
- clonally. - (correct answer)from an unfertilized embryo.
Scientists have confirmed a rare case of a virgin female hammerhead shark giving birth
to offspring that were genetically identical to the mother. What process accounts for this
phenomenon?
- binary fission
- clonal reproduction
- vegetative reproduction
- parthenogenesis - (correct answer)Parthenogenesis
Which statement best describes the cost of meiosis?
- Production of haploid gametes for sexual reproduction has a higher energy cost than
direct production of diploid offspring.
- Males pass on only 75 percent of their genetic material through sexual reproduction
rather than 100 percent through asexual reproduction.
- Sexual reproduction puts individuals at greater risk for predation.
- Females pass on only 50 percent of their DNA through sexual reproduction rather than
100 percent through asexual reproduction.
- Sexual reproduction results in fewer offspring than asexual reproduction. - (correct
answer)Females pass on only 50 percent of their DNA through sexual reproduction
rather than 100 percent through asexual reproduction.
All of the following are benefits of sexual reproduction EXCEPT that
- mutations are more likely to be purged.
- offspring are more likely to possess traits to help cope with future environmental
challenges.
- offspring are likely to have greater fitness than asexually produced offspring.
