Genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is typeAB.
If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents.
So the chance of alleles OO is 25% × 25% = 6.25%,
alleles AA is 75% × 75% = 56.25%,
alleles AO is 75% × 25% = 18.75%,
alleles OA is 25% × 75% = 18.75%.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A.
The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.

Answer:
According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.
Explanation:
According the question
q represent the short legs and 33 of 100 organism have short legs.
As a result the frequency of q with respect to the 100 organism is 33/100
=0.33
Therefore q=0.33
we all know that
(p+q)2=1
∴ p+q= 1
∴ p=1-q
p= 1-0.33
p=0.67
The frequency of p is 0.67
Answer:
a. The chromosomes in a somatic cell of any organism are all morphologically alike FALSE
Somatic cells have autosomal chromosomes and also carry sex chromosomes. These chromosomes are in pairs and each pair is morphologically different from the other pairs because they have differences in the size and the position of the center. It allows them to be differentiated from others, this can be made evident by a karyotype.
b. During mitosis, the chromosomes divide and the resulting sister chromatids separate at anaphase, ending up in two nuclei, each of which has the same number of chromosomes as the parental cell. TRUE
During the anaphase there is separation of the sister chromatids. At the end of the anaphase, a complete set of chromosomes is grouped at the cell's poles. The mitosis process produces two daughter cells with the same genetic material to the progenitor cell.
