So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.
You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
<u>Answer</u>:
- The possible genotypes of the children are Hh and hh.
- The probability of genotype Hh = 1/2
- The probability of genotype hh = 1/2
<u>Explanation</u>:
- <em>Autosomal genes</em> are the genes present on any of the chromosomes except the sex chromosomes.
- An autosomal recessive mutation is the mutation in an autosomal gene which only expresses itself in the phenotype in homozygous condition and affects both males and female equally.
- For the given question, let the autosomal gene be represented by H (dominant) and h (recessive)
- According to the question,
Since the <em>mother</em> is homozygous her genotype would be hh and the <em>father</em> is heterozygous so his genotype would be Hh.
The following cross is made to know the genotypes of the children :
hh X Hh--------> Hh Hh hh hh
So the <em>possible genotypes of the children are Hh and hh as shown in the cross. </em>
Note : An image is attached representing the cross in a Punnett square.
- The probability of an event = No. of favourable outcomes/total no. of outcomes
The probability of occurrence of genotype Hh would be = 2/4 = 1/2
Similarly, the probability of occurrence of genotype hh would be 2/4 = 1/2
Just So you know, <span>The molecular clock, explains Blair Hedges, is a tool used to calculate the timing of evolutionary events. Instead of measuring seconds, minutes and hours, the molecular clock measures the number of changes.</span>
Strong base. Anything below seven is an acid while anything above it will be a base. Seven is Neutral because it is directly in the middle. <span />
