Helping kin raise offspring is one way individuals can increase their inclusive fitness. Imagine there is a family of birds. If any male individual breeds alone, they will have three offspring. If a beta (B) male helps an alpha (A) male, then beta will have no offspring. If an alpha is helped by a beta, then alpha will have eight offspring. At which generation does it no longer benefit beta to help alpha? Generation 1 Generation 2 Generation 3 A A A B B

f you had two guinea pigs of opposite sex, both homozygous, one black and one brown, but you didn't know which was the dominant characteristic, how would you find out the dominant color? Select one: a. Mate them and see what color the offspring are-the other will be the dominant color b. Mate them and see what color the offspring are-that will be the dominant color c. The dominant color could not be determined by mating the two, then mating their offspring; further generations would have to be produced to determine the dominant color d. Mate them together, then mate their offspring to see what color the next generation is-the other color will be the dominant color e. Mate them, then mate their offspring to see what color the next generation is-that will be the dominant color
The gender of an American alligator is determined by the temperature at which the egg incubates. A temperature of 34°C and higher produces male offspring, while a temperature closer to 30°C produces female offspring. Which statement best explains gender determination in American alligator offspring? O The gender of the offspring is determined to keep an even number of males and females in the American alligator population. O The gender of the offspring is determined to ensure a large number of mature females in the American alligator population. O The gender of the offspring is determined as a result of environmental and not genetic factors. O The gender of the offspring is determined as a result of genetic and not environmental factors. hp -> esc & 司

This diagram illustrates a type of reproductive process in an organism. Parent Offspring A Based on this information, what conclusion about the offspring labeled "A" is supported? O It has acquired traits in response to its environment. O It has a lower mass of genetic material than offspring B. O It has the same genetic material as its parent. O It has half as much genetic material as its parent. INTL 01 https://student.masteryconnect.com/#

In some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal? Don't write from any online source..
A Labrador retriever breeder tried to get brown and yellow puppies. She crossed a yellow female labrador with a brown male. To her surprise all the puppies came out black. Explain why this is seen. What are the chances that she will have yellow puppies if she mates two brown Labrador retrivers? Show your work.
In every beehive, there is one queen bee who lays all the eggs. If an egg is not fertilised, it hatches into a male bee, called drone. If an egg is fertilised, it hatches into a lady worker bee, which does not lay any eggs.a. Consider a drone. How many parents, grandparents, great grandparents, great-great grandparents, great-great-great grandparents, great-great-greatgreat grandparents does it have?b. Write a mathematical sentence which can be used to represent the number grandparents a drone has during a particular generation.
In some animal species, being tall is dominant over being short. If a homozygous dominant individual mates with a short individual, what is the chance that their offspring will be heterozygous?
In a natural population it was noticed that some natural variants with different forms, behaviors or physical traits are better at getting through life and reproducing compared to other others. Look at the diagram below, decide which choice best explains why the natural occurring trait is passed on. 1 2 RRORS O Brown fur color in mice blends in with the environment better so the brown mice will survive and pass on their fur color traits O White fur color in mice blends in with the environment better so the white mice will survive and pass on their fur color traits O Both brown and white fur color in mice blend in with the environment well so both types of mice will survive and pass on their fur color traits
Scenario part 1 A population of frogs in the species Goofus frogus (I made this up) are living in a valley within a rainforest. In these frogs, color is controlled by 1 gene. GG frogs are blue Gg frogs are green gg frogs are yellow. Questions part 1 what type of inheritance pattern is described? (______(?)dominance) how many alleles does an individual frog have for the color gene? (answer with a number, no explanation) if a yellow frog and a blue frog had offspring, what genotype(s) could their offspring have? what would the ratios of genotypes be? if two green frogs had offspring, what phenotype(s) could their offspring have? what would the ratios of phenotypes be?
Which statement about an individual that is homozygous for an allele is FALSE? Select one: a. Its parents were necessarily homozygous for that allele. b. Each of the gametes it produces will contain one copy of that allele. c. It will pass that allele to its offspring. d. It is true-breeding with respect to that allele. e. Each of its cells possesses two copies of that allele.
Guinea pigs reproduce with two parents who each contribute % of the offspring's DNA. This means that the guinea pigs offspring receive a part of a gene code from each parent. These can be dominant or recessive and how they combine determines the organism's gene code and If Pinky wants a hairless guinea pig for Christmas, she should find a breeder to sexually reproduce chance to be hairless. because each offspring has a % chance to be hairless
