binary fission?
In binary fission, the parent is split into two daughter cells, each genetically identical while receiving a copy of DNA
The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
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.
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
Explanation:
Answer:
Heterozygous dominant
Explanation:
because, as you know, heterozygous is different, and Dd has both dominant and recessive, making it heterozygous rather than homozygous.
Because the first d is dominant (capital D), then it makes the genotype dominant and heterozygous.
