Ans)Yes there has been evolution in favour of female production. During mating there is no competetion among the females whereas mating competetion do occur among males. This leads to inccrease in reproductive fitness of females.Hence it is a method/adaptation to advance female fitness.
There have been all kinds of evolution in favor of male fertilization, are there any specific...
1. What is often true about the relative rates of phenotypic evolution of sexually selected traits vs most other kinds of traits? 2. In the good genes model, why does a male trait have to be costly in order for the female preference to be maintained by natural selection? 3. Explain the Fisherian (runaway)model of sexual selection –what generates correlations between female preferences and male traits. What kind of experimental observation would support the model? 4. Explain the concept of...
Phishing, Malware, Spyware. Have you been targeted by any of these kinds of attacks? What was the outcome? What kind of attack is it when a bad actor tries to slow or block access to network services?

5. Feral pigeons (Columba livia domestica) have long been considered the most frustrating pest bird. Flocks of these pigeons pose a threat to crops, livestock, and human health as their large numbers can decimate crops and act as disease vectors for pathogens that affect both livestock and humans. However, in places like New York's Washington Square Park, pigeons are well-loved and well-fed members of the community. Controlling these pigeon populations has been a challenge...
Double fertilization in an angiosperm produces a diploid zygote and a haploid polar nucleus. a diploid zygote and a diploid endosperm. a diploid embryo and a triploid zygote. a triploid embryo and a diploid endosperm. a diploid zygote and a triploid endosperm. Which of the following is the correct order of floral organs from the outside to the complete flower? petals-sepals-stamens-carpels sepals-stamens-petals-carpels spores-gametes-zygote-embryo sepals-petals-stamens-carpels male gametophyte-female gametophyte-sepals-petals Why is sexual reproduction important? It allows animals to conserve resources and reproduce...
How do you think dysfunction of the male and female reproductive organs can affect reproduction? How would you support your patient that was experiencing infertility? What experience if any have you had with this?
Suppose that 6 female and 5 male applicants have been successfully screened for 5 positions. In how many ways can 4 females and 2 males be selected? 155 6.150 Oc 48 . 180 30
We have discussed the role of meat consumption in hominin evolution as an important source of fuel for our oversized and metabolically costly brain. Do you think the expensive tissue hypothesis has merit? Why or why not? Can you think of any alternative hypotheses to explain the trend towards larger brain size over the past 2.5 million years?

Human evolution has been the topic of the videos and discussions during this semester. We have followed our species from its earliest appearance to the present. You have also learned about different types of cultures around the world that descended from the most initial interactions among ancestral human groups. What do we think was the most critical, pivotal moment in our history that changed our species forever? How did it change us, and what have been the implications in culture...
. Male drosophila typically have a higher potential reproductive output than females because a. The more females fertilized, the higher the male's fitness b. Females are limited by the resources that they have to use to produce eggs c. Males do not provide any parental care d. All of the above e. None of the above 2. The handicap theory of mate choice in sexual selection says that : a. Male display genes spread and female choice genes only spread...
