Do brothers have different alleles?
Each sibling has 50% of the same genes as each parent, but the variety of possible allele combinations gives a range of reliability between siblings. Taking an average of the percent relatability between siblings gives you 50%. The only example of siblings that share 100% of their DNA are identical twins.
Can alleles influence each other?
The alleles of one gene can interact in several different ways at the functional level, resulting in variations in the type of dominance and in markedly different phenotypic effects in different allelic combinations.
How do multiple alleles affect phenotype?
Having more than 1 or 2 alleles for a trait can greatly increase the number of phenotypes, depending on the trait’s specific pattern of inheritance. For example, human blood type is controlled by 3 alleles (just referring to the ABO blood groups here): A, B, and O.
When different alleles of the same gene are present in an individual it is a?
heterozygous
If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
Will two brothers who have been raised in different environment have the same Behaviour give reason for your answer?
Answer: No if the environmental condition is totally different then the behaviour of the brothers will totally different. Is one brother brought up into very cold temperature and the other one brought up into a very hot climatic condition then obviously they behave differently.
Will two sisters brought up in different environments behave in a similar way?
Yes, two sisters brought up in different environments will behave in a similar way. Since Saroja and Suvasini are twin sisters, therefore, their facial features eyes, height etc. are common i.e. they resemble to each places, as a result the other qualities which they adopted later on different.
