Answer:
Binary Fission would be correct I think.
The disk part of the galaxy.
Answer:
10% of progeny would have wild type phenotype
Explanation:
True breeding fly with wild type wings and small eyes: De/De
True breeding fly with downward wings and wild type eyes: dE/dE
Cross between them : De/De X dE/dE = De/dE ( F1 )
Recombination frequency = 20%
Next cross, De/dE X de/de =
De/de = parental = 40%
dE/de = parental = 40%
DE/de = recombinant = 10%
de/de = recombinant = 10%
The third genotype i.e. one of the recombinant genotypes will have the wild type makeup ( DE/de ) hence 10% of flies would have wild type phenotype.
Answer:
explained
Explanation:
The skin cells divide every day, as the epithelial layer is the outer protective layer, it needs to be replaced from time to time, which helps in healing wear and tear. Our skin cells divide once in each day.
In contrast, the nerve cells do not divide at all. That is their frequency of cell division is zero. They cannot divide because they lack centriole in them.
