Answer: No, only identical twins will look identical.
Explanation:
Identical twins are also called monozygotic twins. Such twins are produced by the fertilization of one egg that splits into two. The genes present in these twins are same thus the expression of traits is also same in them and they have the same sex.
Sam and Joe and Maria and Ella are identical twins these pairs are expected to have same genotypic and phenotypic traits. They may be clones of each other. But if Sam and Maria are married and Joe and Ella are also married then their children will have some similar traits in common but their children will not be identical as they are not identical twins as their parents were.
Answer:
There are many types of challenges are faced by the scientists in 21st century. some are as given below:
Explanation:
1. Getting biodiversity. We're losing species at a disturbing rate, and we have to comprehend what the implications of that may be.
2. sustainable development. Like feasible agriculture, yet more broad sense. Discovering approaches to accommodate human needs while limiting the mischief we cause to the earth is urgent.
3. Everything about hereditary qualities. It's simply so much fun.
4. The most effective method to cut across political, social, and social limits and spur enormous and little scope activity to lessen biodiversity loss. This point may have a hefty sociology component, yet it's significant. All the natural and biological information on the planet won't make any difference on the off chance that we can't get individuals to follow up on it.
Answer:
3 molecules of water and use glycerol and fatty acid reactants
Answer:
It depends on the specific cell type that suffers the mutation. For example, in stem cells, it is reasonable to expect that mutations in the genes involved in DNA replication will have critical consequences
Explanation:
A mutation is a genetic modification in the DNA sequence due to errors during the mechanism of DNA replication or by the effects of environmental (mutagenic) factors. A mutation in the germline can be inherited in the next generations, while a mutation in somatic cells is not inherited. Moreover, a mutation affecting RNA synthesis may have diverse effects depending on the function of the gene involved in this mutation. In a similar mode, a mutation in one gene associated with the mechanism of DNA replication can have critical consequences on the cells originated from the mutated parental cell, but again it is variable and generalizations can not be made without knowledge of the cell type suffering this modification.
