Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.
Polygenic traits occur because of genes and environment. There are usually two or more genes involved in these traits. It also takes into consideration where the organism lives, for example the fact that some hotter areas have a history of people with darker skin tones.
What are some causes of accidents in the dining room
Yes. There are some traits like skin color that are controlled by multiple genes within an individual. There is also a problem called nondisjunction that causes a gamete to wind up with two chromosomes instead of one. The offspring then has three chromosomes and three genes for each trait carried on that chromosome. (Nondisjunction of the 21st chromosome causes Down Syndrome, so someone with Down Syndrome has three genes for each trait on the 21st chromosome.)
All protists are eukaryotes, some are heterotrophic, some are autotrophic, almost all can move, and almost all are single celled. No, we need traits that ALL of them share, not just some or almost all.
Shy Smart, Humble, and he was a pacifist.
This is because phenotypes are the physical appearance. If you had brown hair and so did I, our phenotypes, would still be different.
i don't know but i think it is because of the recessive and dominate traits.
Usually, traits have a large variety of phenotypes because they have a large amount of genes.
Because these are governed by quatitative or multiple genes
some human traits show a large number of phenotype because the traits are controlled by many genes. The genes act together as a group to produce a single trait
The garden pea has a few advantages for his experiments. It has a short generation time thus he can study many pea plants at once. Also their phenotypes are very distinct - which is a bonus since the whole experiment is to observe distinctive phenotypes - would be too vague and confusing if the traits are too close alike. The phenotypes that are distinctive are by color, the growth, round/wrinkled peas etc. Mendel's experiment basically fathered genetics. He knew nothing about alleles and DNA and what not yet he was still able to show how traits are inherited. He obviously proved that traits come from alleles - that traits don't just mix and are forever lost because some traits can be recovered (Homozygous x homozygous will always give homozygous. However Heterozygous Tt x Tt can recover the recessive trait, tt).

by natural selection.
because no one in this world has the same gene.They may have similar gene,but not the same
No, the traits Mendel studied (by chance) were all controlled by single genes. There are some traits that depend on interactions between multiple genes, sometimes even on different chromosomes. The phenotypes they generate are much more difficult to match to genotypes and inheritance than Mendel's laws directly explain.
Moon Jellyfish is the most common. Some of the more poisonous types include the Portuguese Man O' War, the Box Jellyfish, and the Irukandji. There's a type of giant jellyfish in Japan that I don't remember the name of, but it would probably be easy to find.
Phenotypes that are more advantageous for survival and reproduction in a given environment are more likely to be passed on to future generations, leading to their increased frequency in a population over time. This process is driven by natural selection, where individuals with beneficial traits have a higher chance of passing on their genes. Additionally, genetic drift, gene flow, and mutations can also influence the frequency of phenotypes in a population.
