In asexual reproduction the daughter cell will have the same genetic composition as the parent cell. In sexual reproduction the genetic composition will be a combination of both parents.
Answer:
The statistics
Explanation:
Mendel experiments were different because he used peas because they were cheap, they grow relative fast, they have different kind of plants, that mean that he can focus in one characteristic at a time, like the color, the shape, the texture, etc.
So since he can do numbers with his results, the statistics were easy to do, were easy to observe the patterns in real life so he can do in theory other traits even in humans.
Hope this info was useful.
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
It is possible if the parents are heterozygous (meaning they have a dominant AND recessive allele for the trait.
Well say the allele for orange is X and the allele for green is X.
Let’s say we have two homozygous orange parents. That means they have no trace of green.
XX
X XX XX As you can see, the Punnett
X. XX XX. Square shows that all offspring will have capital X’s, meaning only homozygous orange offspring is produced. No green babies here.
We can try the same thing with a homozygous parent and a heterozygous parent.
Xx
X XX Xx Here we can see that 50% of
X XX Xx the offspring has a lowercase x. That means they are heterozygous. They carry the green trait, but it doesn’t show because it is masked by the dominant orange allele. So no green babies here either.
Finally we can try heterozygous parents.
Xx
X XX Xx 25% of the offspring is
x Xx xx homozygous for orange. 50% of the offspring is heterozygous for orange. And 25% is homozygous for green. There must be two recessive alleles in order for green to show.
The only way to produce green offspring is to have two heterozygous parents.
