A. Women can be carriers because they can be heterozygous for the trait
Some times, if it's a recessive trait, women can carry it but not be affected by it.
B. X-linked traits are more common in men
Men only have one X gen, if it's a recessive trait and men inherit it will be affected by it.
C. Males are never carriers since they only receive one X chromosome
True. Because what we explain in option B, men can't be carriers only been affected by it.
D. Males inherit X-linked traits from their fathers
From its mother, if it's a carrier.
E. Women only have to have one affected gene to show the trait
Only if it's a dominant trait. If it's a recessive one, to show it, it would need two affected genes.
Invasive species can either replace an organism from the ecosystem food web or replace it.
Explanation:
- Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
- Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
- So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.
