- 1.What does a male cricket need to be able to reproduce? 2. Is calling good or bad for a cricket's fitness? 3. Give some examples of selection at work in this cricket story. 4. How does selection favor calling? (When is calling a good thing?) a) How does selection favor not calling? (When is not calling a good thing?)Living things that are well adapted to their environment survive and reproduce. Those that are well adapted don't survive and reproducer. An adaption is any characteristics that increase fitness,which is defined as the ability to survive and reproduce. What characteristics of the mice is an adaptation that increased their fitness?Please answer this question correctly: True or False: The traits of individuals who produce more surviving offspring spread through the population.
- Reproduction is important because _____. A) it pass on genes adapted genes to future generation ensuring survival B) it maximizes individuals survival C) it is the key for individuals success D) life is nothing without sexA dog breeder thinks that he will be able to charge higher prices for extra-tiny versions ofsmall dogs. He starts off by trying to selectively breed smaller Yorkshire terriers. The averageadult mass of the terriers in his kennel is 2.5 kg. He selects a subset of the smallest dogs to foundhis new tiny dog line. The average mass of the 20 selected dogs is 1.8 kg. He chooses matedpairs randomly from that pool of 20 dogs and rears the resulting puppies to adulthood. Theaverage mass of these offspring was 2.4 kg. Disappointed with the results, the breeder wantsyour help in figuring out where his plan went wrong. 5a.What is the narrow-sense heritability of body size in his population of dogs? 5b. You examine his records and calculate the total phenotypic variance VP across his wholestarting population of yorkies to be 1.1. What is the additive genetic variance VA in thispopulation? 5c. The breeder clearly kept very good records of dog size measurements across the pedigrees inhis…Do mutations in body cells contribute to genetic variation? No, the causes of body cell mutations are outside the body and cannot alter DNA. Yes, these body cell mutations lead to mutations in the gametes. No, the mutations cannot be passed to offspring and only affect the individual. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
- Birds are more likely to form pair-bonds than mammals because … Group of answer choices: A. Bird reproductive physiology makes it easier to judge paternity certainty B. Flight makes it easier to find mates C. Bird species are unable to defend critical resources the way mammals can D. Male mammals have higher levels of testosterone making them more likely to fight E. Either bird parent can sit on the nest or feed chicks while the chicks are too young to flyImagine you are a scientist observing rats in the wild. As the rats reproduce, rats born with white fur slowly begin to outnumber rats with black fur. In three to five sentences, provide two or more different explanations of why the rats with white fur might be outnumbering the rats with black fur.1.) Lynx mate in March and have litters of 3 to 5 kittens in May. Lynx kittens are born blind and naked . Their eyes open after 10 days. In 12 weeks , the kittens travel with their mother. They watch and learn how to hunt for hares. Their eyesight is more acute than their hearing or sense of smell. Lynx are active at night (nocturnal). Hares have litters of 2 to 4 offspring, with up to 4 litters over a summer. Hares are born with their eyes open and bodies fully haired. Birth weight doubles in 8 days. Hares use their good hearing and super sensitivity to ground vibrations, as well as speed and coordination, to escape lynx. Hares are active at night and spend the day grooming and resting. A.) Classify the lynx as a r- or K-selected species . Provide evidence from the information given to support your choice .
