There are 3 things that can be harmful if it reduces the organisms for survival and reproduction. The three things are changes in DNA, changes in phenotype and mutation .

Explain why most animals are born without harmful inherited traits?

Most animals do not have harmful inherited traits because natural selection tends to eliminate genes that are detrimental to survival and reproduction. Over time, individuals with harmful traits are less likely to pass on their genes, resulting in a population with fewer harmful inherited traits. Additionally, genetic variability and recombination during reproduction help dilute the prevalence of harmful traits in offspring.


How does positive vs negative selection pressure influence the evolution of a species?

Positive selection pressure favors traits that increase an organism's chances of survival and reproduction, leading to the evolution of beneficial traits. Negative selection pressure, on the other hand, eliminates traits that decrease an organism's chances of survival and reproduction, resulting in the removal of harmful traits from a population. Overall, positive selection pressure drives the evolution of advantageous traits, while negative selection pressure helps to maintain the fitness of a species by removing detrimental traits.


What are the pros and cons of sexual reproduction in terms of genetic diversity and evolutionary adaptation?

Sexual reproduction allows for genetic diversity through the mixing of genetic material from two parents, increasing the chances of beneficial traits and adaptations. This can lead to faster evolutionary adaptation and better survival in changing environments. However, it also carries the risk of harmful mutations and the dilution of advantageous traits through recombination.


Why are autosomal dominant disorders rare in the general population?

Autosomal dominant disorders are rare in the general population because individuals with these disorders typically have a 50 chance of passing on the mutated gene to their offspring. This means that the disorder can be quickly eliminated from a population if affected individuals have fewer children or if the mutation is harmful enough to reduce the chances of survival and reproduction.


What are the advantages of sexual reproduction in biology?

Sexual reproduction leads to genetic diversity in offspring due to the random combination of genes from two parents, which can result in increased adaptation to changing environments and enhanced survival chances. It also helps in eliminating harmful mutations and allows for reshuffling of genes to create new combinations, contributing to evolutionary processes.

Why is the diversity of life on earth possible by sexual reproduction?

Sexual reproduction allows for genetic recombination between two organisms, increasing genetic diversity among offspring. This variation helps species adapt to changing environments and increases their chances of survival. Additionally, sexual reproduction can mask harmful mutations by diluting their effects among offspring.

What does sexual reproduction provide for?

Sexual reproduction provides genetic diversity, allowing for variation in offspring which can increase the chances of survival in changing environments. It also allows for the combination of different traits from two individuals, enhancing the overall fitness of the population. Additionally, sexual reproduction can help in the elimination of harmful mutations through genetic recombination.


A mutation is helpful depending on whether it makes the living thing?

A mutation is considered beneficial if it confers a selective advantage that improves the organism's chances of survival and reproduction in its environment. Harmful mutations typically decrease an organism's fitness and can be detrimental to its survival. The impact of a mutation on an organism's survival depends on the specific environment and circumstances in which it finds itself.


What are chemophiles?

Chemophiles are organisms that thrive in environments with high concentrations of chemicals or toxins that would be harmful to other organisms. These organisms have developed adaptations to utilize or tolerate these chemicals for their survival.


How does positive vs negative selection pressure influence the evolution of a species?

Positive selection pressure favors traits that increase an organism's chances of survival and reproduction, leading to the evolution of beneficial traits. Negative selection pressure, on the other hand, eliminates traits that decrease an organism's chances of survival and reproduction, resulting in the removal of harmful traits from a population. Overall, positive selection pressure drives the evolution of advantageous traits, while negative selection pressure helps to maintain the fitness of a species by removing detrimental traits.


Why do organisms favor sexual reproduction?

1. The Random Distribution of Chromosomes in Metaphase I Homologous chromosomes arrange themselves randomly at the equator of the spindle randomly in metaphase I.The consequent random assortment of chromosomes makes new genetic combinations. 2. Crossing Over of Homogolous Chromosomes 3. Mutation


What sexual reproduction give species?

Sexual reproduction allows for genetic diversity in a species by combining the genetic material of two individuals to create offspring with unique combinations of traits. This diversity increases the chances of survival and adaptability in changing environments. Additionally, it can help eliminate harmful mutations and increase the overall fitness of the population.


Why is benzoquinone production considered an adaptive trait for plants?

Benzoquinone production in plants acts as a natural defense mechanism against herbivores and pathogens due to its toxic properties. This adaptive trait helps deter feeding by herbivores and inhibit the growth of harmful pathogens, increasing the plant's chances of survival and reproduction.


What characteristic of sexual reproduction has specifically favored the survival of animals that live on land?

The genetic diversity generated through sexual reproduction allows for adaptation to changing environments, which is crucial for animals living on land where habitats can vary significantly. Additionally, sexual reproduction helps in repairing DNA damage and reducing the accumulation of harmful mutations, which is particularly important for organisms exposed to potentially damaging conditions on land.


What are some advantages of reproducing sexually?

Sexual reproduction allows for genetic diversity through genetic recombination, increasing the chances of species adaptation and survival in changing environments. It also helps in removing harmful mutations and decreasing the likelihood of genetic disorders. Finally, sexual reproduction promotes the spread of beneficial traits through gene mixing.
