Some of the squirrelfish are carriers of a recessive gene that codes for a yellow color instead of red.

A population of red squirrelfish breeds and produce offspring 75 are still red but 25 are yellow. This variation in the color of the squirrelfish can be explained by?
Some of the squirrelfish are carriers of a recessive gene that codes for a yellow color instead of red.
In sexual reproduction an offspring is produced with genes from both parents When the offspring has a new genetic variation that it got from neither of its parents it is called an?
The offspring is called a "mutant" if it has a new genetic variation that it did not inherit from either parent. Mutations can arise spontaneously or be caused by environmental factors, and they contribute to genetic diversity within a population.
Is the hippo able to pass on variation to offspring?
Yes, any animal that undergoes sexual repoduction can pass on variation to their offspring, provided that variation is contained in the gametes, or germinative cells.
How do you ensure variation in offspring?
Variation in offspring is ensured through the process of sexual reproduction, where genetic material is mixed from two parents to create unique combinations of genes in the offspring. This variation is further increased through the random assortment of genes during meiosis and genetic recombination. Mutations in DNA also contribute to genetic diversity and variation in offspring.
Why is there variation?
the change that occur from parents in the offspring
The fact that an organism's offspring are not identical is known as?
The fact that an organism's offspring are not identical is known as genetic variation. This variation arises due to the combination of genetic material from both parents during reproduction, leading to differences in traits among offspring.
What are the four major points of the theory of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
What does variation in offspring mean in evolution?
Variation in offspring refers to the differences in traits and characteristics among individuals within a population. This variation is essential in evolution as it provides the raw material for natural selection to act upon, leading to changes in the gene pool over generations. It increases the chances of some individuals being better suited to their environment and thus more likely to survive and reproduce.
What does variation result from sperm and egg?
Variation results from the combination of genetic material from the sperm and egg during fertilization. Each sperm and egg carries a unique set of genes, leading to genetic diversity in the offspring. This genetic variation is important for evolution and adaptation in a population.
How can mutation lead to evolution in a population?
Mutation introduces variation in the genetic material of individuals within a population. This variation can result in different traits that may provide a survival advantage in a particular environment. Over time, individuals with beneficial mutations are more likely to survive and reproduce, passing on these advantageous traits to their offspring, ultimately leading to evolutionary change in the population.
Sexually reproducing species show greater variation than asexually reproducing species due to?
the shuffling of genetic material through sexual reproduction, which introduces new combinations of genes and increases genetic diversity in offspring. In contrast, asexual reproduction produces identical offspring through mitosis, resulting in less genetic variation within the population.
What are Darwin's four postulates?
Individuals within a population have variation in traits. Some of the variation in traits is heritable. Individuals with certain traits are more likely to survive and reproduce. Over time, the frequency of traits that are advantageous for survival and reproduction will increase in a population.
