Answer: the same.

My explanation: Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.  Additionally, manipulation of chromosome number is routinely used by ...

If a mother has a blood type AB+- and her father has a blood type B- and she marries a man with O- blood type. What is the perce
Marina CMI [18]
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 -.

What does a line in between two individuals represent?
OlgaM077 [116]

Answer:

In a pedigree chart, the line which is horizontal shows the parents which mated and produced the children which are represented in the vertical lines below them.

A pedigree chart can be described as a diagram which illustrated the sequence of ancestors of an individual. Often, a pedigree chart is used to look for genetic traits or genetic disorders which might run in the family history. Pedigree charts are important for understanding the probabilities of the offsprings in which a genetic disorder might occur due to family history.
