Answer: where's the graph?
Answer:
The young man is not the son of Howard Hughes.
Explanation:
The human blood system works on codominance type of inheritance in the case of blood group A and blood group B present together however, in blood group O it still follows the law of dominance as antigen O is recessive in present of any other antigen.
We know Howard Hughes had blood type AB
So, the genotype would be - IAIB
We also know that the mother of the young man claiming has a blood type A
So, possible genotypes would be - IAIA (case 1) or IAi (case 2)
For case 1,
The possible genotypes for the man claiming would be
IAIB X IAIA --------> IA IA, and IAIB.
According to case 1, he is not the son of Howard.
For case 2,
The possible genotypes for the man claiming would be
IAIB. X I A i ---------> IA IA , IAIB I A i and IB i
Both cases show that the man claiming is not the son of Howard as the blood group of the man is O and the genotype should be ii.
Answer:
1/4
Explanation:
In order for a plant to be short and yellow, it needs to have hοmοzygous lowercase letters for height and color.
If the plant had one capital letter for either height, color, or both, this would dominate the recessive gene and would not allow the plant to exhibit the recessive trait.
The short, yellow plant has a genotype of:
The plant that is heterozygous for both traits means that its genotype has both the dominant (capital) and recessive (lowercase) letters.
The heterozygous plant has a genotype of:
We can use a dihybrid crossing of alleles in a 4x4 Punnett square. To figure out which four pairs of alleles to use for crossing, we can FOIL the genotypes of the two plants getting crossed.
- (tt) · (gg) = tg + tg + tg + tg
- (Tt) · (Gg) = TG + Tg + tG + tg
Use these pairs of alleles to cross in the Punnett square. To see which offspring will be short and green, we need to look at the pairs of alleles for the height and color traits separately.
Short plants must have the genotype of tt.
Green plants can have the genotype of GG or Gg.
Look at the Punnett square to see which genotypes are hοmοzygous for the short trait and either hοmοzygous or heterozygous for the green trait.
We can see that the third row of genotypes consist of ttGg, which corresponds to the short and green phenotypes.
Therefore, 1/4 of the offspring will be short and green.
The administration of prepared antibodies such as those in breast milk is an example of passive immunity.
<h3>
What is passive immunity?</h3>
when the prepared antibodies are directly given to protect the body against foreign agents is called passive immunity.
during the initial days of lactation, the yellowish fluid colostrum is secreted by the mother. it contains abundant IgA-prepared antibodies. during breast milk, it contains these antibodies that give immunity to the infant. it fights against the pathogen. these are an example of passive immunity.
