Principle of Inheritance and Variation

Euploidy is best epplained by
1 Exact multiple of a haploid set of chromosomes
2 One chromosome less than the haploid set of chromosomes
3 One chromosome more than the haploid set of chromosome
4 One chromosome more than the cliploid set of chromosomes
Explanation:
: Euploidy is best explained by exact multiple of a haploid set of chromosomes. Euploidy is presence of complete haploid sets of chromosome in multiples.

Mutation is more common when it is present in:
1 dominant condition
2 recessive condition
3 constant in population
4 none of the above
Explanation:
: Mutation is more common when it is present in dominant condition because in this conclition the gene express itself and suppress the expression of another allelic gene.

The major cause of evolution of genes and protein is
1 point mutation
2 chromosomal aberration
3 sexual reproduction
4 gene duplication and divergence DUIMET-2010
Explanation:
: Point mutations involve small changes in the DNA sequence, such as the substitution of one base pair for another. These mutations can lead to variations in genes and proteins, contributing significantly to the process of evolution by introducing new traits and diversity into populations over time.

The point mutations A to \(\mathrm{G}, \mathrm{C}\) to \(\mathrm{T}, \mathrm{C}\) to G and T to A in DNA are:
1 transition, transition, transversion and transversion respectively
2 transition, transversion, transition and transversion respectively
3 transwersion, transversion, transition and transversion respectively
4 all four are transition
Explanation:
: A to G and \(T\) to \(A\) mutations are transitions because they involve changes within the same category of meleotides (purines). \(C\) to \(T\) and \(C\) to \(G\) mutations are transversions bacause they involve changes between different categories of meleotides (pyrimichines to purines).
2 One chromosome less than the haploid set of chromosomes
3 One chromosome more than the haploid set of chromosome
4 One chromosome more than the cliploid set of chromosomes
Explanation:
: Euploidy is best explained by exact multiple of a haploid set of chromosomes. Euploidy is presence of complete haploid sets of chromosome in multiples.
