Answer:
Brain makes your movements but heart is what makes you live so its really up to you to choose which one you find more important both are necessary though so whether you pick brain or heart you will get a good grade as long as you explain why you choose it
Explanation:
The recombination frequency of the two gene pairs is 3%.
The number of recombinant offspring(r.o.) / total number of offspring x 100% = recombination frequency(θ):
r.o./total x 100% = θ
30/100 x 100% = 3%
Recombinant offspring are children that have a different allele combination to their parents.
For example, say a mother has a haploid cell with the alleles AB and the father has a haploid cell with the alleles ab. These combine to make a diploid cell with the sequence Aa+Bb.
Formation of Recombinant Offspring :
Recombination can happen in two different ways; independent assortment and crossing over.
- Independent assortment is when the maternal and parental DNA are mixed during meiosis, creating a new gene sequence.
- Crossing over happens during the first stage of meiosis when the two homologous chromosomes are paired and a portion breaks off on the same loci then reconnects to a different end. Crossing over can only happen when there isn't a physical linkage of the parental alleles.
Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis. A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way we can measure the genetic distance between two loci, based upon their recombination frequency. This is a good estimate of the real distance. Double crossovers would turn into no recombination. In this case we cannot tell if crossovers took place. If the loci we're analysing are very close (less than 7 cM) a double crossover is very unlikely. When distances become higher, the likelihood of a double crossover increases. As the likelihood of a double crossover increases we systematically underestimate the genetic distance between two loci.
When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

Answer:
Each daughter cell will have 46 chromosomes.
Explanation:
Because a chromosome becomes 2 chromosomes when split into two, the parent cell is still giving ech daughter cell thge same amopunt of choromsomes as it has.
Answer:
Cell theory is originally presented by Schleiden and Schwann and initially, it has only two points and after some time the third point added but with the discoveries in the field of biotechnology there are many other points that are accepted and known as the modern cell theory.
According to the cell theory, all organisms are made up of one of the multiple cells and arise from the pre-existing cells by the cell division. A cell is a basic unit of structure and function.
Other than these three there are several other points are drive with the help of discoveries regarding discoveries which is helping to form that DNA is the hereditary material that passes all necessary information to the next generation.
