Question

which sentence in the passage points out the similarity between parthenogenesis and sexual reproduction? parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.

Explanation:

To find the sentence showing the similarity between parthenogenesis and sexual reproduction, we analyze each sentence:

• "Parthenogenesis is a type of reproduction that does not require a mate." → Describes a difference from sexual reproduction (which usually needs a mate).
• "It’s rarely seen in birds and higher vertebrates." → Describes occurrence, not similarity.
• "Parthenogenesis involves the formation of a zygote." → Sexual reproduction also involves zygote formation (from fertilization), so this shows a similarity.
• "But this zygote is formed without fertilization." → Describes a difference from sexual reproduction (which needs fertilization).
• "In parthenogenesis, in the absence of a male gamete, the ovum develops directly into the zygote." → Describes parthenogenesis process, not similarity.

Answer:

Parthenogenesis involves the formation of a zygote.
