An evolutionary barrier that could cause an infertile offspring is genetic incompatibility between the parents, leading to mismatched or non-viable offspring. This can occur when different species attempt to reproduce, resulting in a hybrid that is infertile. Additionally, mutations or chromosomal abnormalities can also lead to infertility in offspring.
What else can I help you with?
What is the diploid number of a mule and why is it that they are infertile?
The diploid number of a mule is 63. Mules have an odd number of chromosomes (63) - which means that the chromosomes do not pair off properly. This causes problems with meiosis, which is the process that creates the gametes (sex cells) that will be involved in sexual reproduction. This is why almost all mules are infertile. Mules are the result of a cross between two species. By definition, the offspring from two different species cannot be fertile. However, there are a few very rare cases of a female mule having a viable offspring.
What kind of reproduction causes variation in organisms?
Sexual reproduction causes variation in organisms because it involves the mixing of genetic material from two parents, resulting in offspring with a unique combination of genes. This variation is essential for the adaptation and evolution of species over time.
Is the following statement true or false crossing over causes the offspring to be different from the parent?
True. Crossing over is a genetic process during meiosis where chromosomes exchange segments of DNA. This creates genetic variation in the offspring, making them different from their parents.
If you cross a homozygous dominant striped cat with a homozygous recessive spotted cat. What will be the phenotype of the hybrid offspring?
The phenotype of the hybrid offspring will be striped, as the dominant striped trait will mask the recessive spotted trait in this case. The genotype of the hybrid offspring will be heterozygous for the striped trait.
What type of reproduction causes the most diversity in offspring?
Sexual reproduction typically causes the most diversity in offspring because it involves the mixing of genetic material from two parents to produce unique combinations of genes in the offspring. This variation increases genetic diversity, which can be beneficial for a population's ability to adapt and survive in changing environments.
Do cat's hairs make women infertile?
No, it is not true that cat hair causes a woman to be infertile. This is nothing but an old wives tail.
What are two causes contributed to dust bowl?
Drought, and infertile land
Causes of infertile soil?
In fertile soil is caused by the absence of the necessary nutrients and sufficient minerals within the soil.
What causes reflux?
Changes in the barrier of the stomach and esophagus.
What is a infertile hybrid?
It is most common when two organisms of different species attempt to reproduce. The combination of genes is usually not fully functional meaning that the offspring is unable to reproduce itself. This can also occur in plants although to a lesser extent as plants are capable of polyploidy. In humans polyploidy causes complicated genetic diseases.
What forms offspring similar to parent?
Sexual reproduction produces offspring similar to parents. Asexual reproduction causes the offspring to be exactly the same as the one parent.
What is a wave bouncing off a barrier called?
When a wave bounces off a barrier, it is called reflection. This phenomenon causes the wave to change direction upon impact with the barrier.

Contrast immediate and ultimate causes of behavior?
Immediate causes of behavior refer to the specific stimuli or events that directly trigger a behavior, such as hunger causing someone to eat. Ultimate causes of behavior, on the other hand, are the underlying evolutionary or environmental reasons why a behavior exists, such as eating being necessary for survival and reproduction. Ultimate causes focus on the long-term evolutionary reasons for behavior, while immediate causes focus on the immediate triggers.
What are the probable causes of testes not dropping?
If the testes don't descend (drop) after birth, then the male can become sterile (infertile), and the risk of testicular cancer increases.
What is incident wavefront?
The incident wavefront is the crest of the wave before it hits a barrier which causes it to reflect
Should we build or not build barrier islands?
no people should not build on barrier islands because it causes soil erosion... and soil erosion is bad :) hahaha be an erosion freee world
