Under What conditions would two offspring have the same genotype and phenotype?

Question

This is a biology question pertaining to the development of a baby.

Answer 1

Genotype is the combination of allelles, either dominant or recessive.

Phenotype is what trait is expressed (such as tall, short, etc.)

Any time two children are born and they have the save parents, they have the same probabilities of having the same genotypes and phenotypes.

For example: If the mother is AA and the Father is Aa for tallness, where tallness is dominant, there is a 50% chance that the child will be AA genotype and tall (phenotype) and 50% chance that the child will be Aa (genotype) and tall (phenotype).

If these children are born at different times, then they run these odds of being born with the same genotypes/phenotypes.

If these children are born at the same time, but are fraternal twins, then they have the same odds as if they were born at different times.

If these children are born at the same time, but are identical twins, then they would have a 100% chance of having the same genotype and phenotype.

This scenario holds true regardless of the genotypes of the parents, the only thing that changes are the percentages.

Each birth (separate and/or fraternal) is like the tossing of a coin....the odds are the same on each toss.

Identical twins will always be 100% genotype/phenotype identical because they are the result of one egg and one sperm.

Answer 2

The chances of two offspring, even twins or clones of the original parent, having the same phenotype are basically zero. As you know, offspring receive a set of genes from each of their parents. What many people don't realize is many genes are switched off (or on) early on.

It is a common misconception that identical twins, which have have the same genotype, also share an identical phenotype. This is NEVER the case (though their phenotypes are very similar). An example commonly used to demonstrate this fact is the difference in fingerprints.

Clones also have the same genotype as the parent, but many cases of animal cloning have demonstrated that the phenotype of the offspring often does not resemble that of the parent!

Savings and Clone (I'm not making up the name), a company that promised to replicate beloved pets, went out of business a few months ago. One of the problems such a company faces is that identical genotype does not translate into identical phenotype.

Answer 3

you do no longer ought to have confidence in a literal Adam and Eve to have confidence that human beings are sinful. the entire "fall of guy" tale can particularly be taken as a metaphor for the form of human expertise and the ensuing duty to make ethical judgements. If the only Christian theology you have been uncovered to is the dumbed-down literal belongings you in all risk have not have been given any concept how the greater smart Christians think of of it, yet there is truthfully no reason to have confidence in a literal "unique sin" to have confidence that human beings fall short and choose the thank you to be restored to oneness with God. The "blood for sins" element of the story isn't inevitably taken as literal, the two. i've got run into lots of Christians who do no longer have confidence that there became some sort of literal magic that befell on the dying of Jesus, redeeming the sins of human beings; particularly that Jesus coming to earth in human form and suffering simply by fact something individuals did provided a skill for human beings to repair a relationship with God in spite of their flaws.

Answer 4

Twins

Answer 5

They'd have to be identical twins, both arising from the same fertilized egg.

Answer 6

if they are both twins...or if the parents have the same blood group
