regulation in the human body. The role of vitamin D is shown in orange. Vitamin D is carried in the bloodstream to the liver, where it is converted into the prohormone calcifediol. Circulating calcifediol may then be converted into calcitriol, the biologically active form of vitamin D, in the kidneys.

The chemical reaction equation of photosyntesis is shown here:
ANEK [815]

Answer:

The 6O2 is left out.

Explanation:

The reactants has 18 oxygens but the products only has 6 oxygens. Adding 6O2 would get us to 18 oxygens on both sides.

This is not part of the equation, but energy could be considered as well.

Homologous chromosomes are similar in all of these characteristics except:
Gnesinka [82]

Answer:

Except alleles

Explanation:

Alleles are different versions of the same gene and that's because they have different DNA, even though it is slightly different it can make a lot of changes so that's why they have different alleles.

Allele is actually the variant form of some genes.

The best<u> example </u>for alleles we can find in the gene for blossom color in some species of flowers or plants. Only one single gene is controlling the color and we can see sometimes different versions of it. Those different versions are called Alleles.

You perform the following dihybrid cross: A blaBx Ab/aB. The A and B genes control different traits. What phenotypic ratio would
Luda [366]

Answer:

Option-D

Explanation:

In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.

1. Unlinked genes

Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which  

1. A_B_ are 9

2. aaB_ are 3

3. A_bb are-3

4. aabb- 1

Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.

2. Linked genes

When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are-  Ab and aB and the recombinant frequency will become less.

Crossing these allele will  form Aabb , AaBb , AaBb  and aaBB  genotypes. The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.

Thus, option-4 which states that the unlinked ration is  9:3:3:1  and linked ratio is  <9: >3: >3: <1 is correct.
