Answer:
C
Explanation:
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Answer:
No, because cell division is expected to decrease not only the net amount of cyclin molecules in daughter cells but also the volume of these daughter cells compared to the original parent cell, and therefore the concentration should be nearly equal.
Explanation:
When a cell divides to produce two daughter cells, the cell components including its previously duplicated genetic material (DNA), organelles, signaling molecules, fatty acids (lipids), proteins, etc., are distributed into daughter cells. These daughter cells have a smaller volume compared to the original parent cell. In consequence, the concentration of cellular components (including cyclin proteins) should be similar between parent cell and daughter cells.
If grey feathers is a recessive trait, then 72.8% of the population is heterozygous for this trait.
Explanation:
The concept used here is of Hardy Weinberg principle, +2pq =1
The homozygous dominant genotypeis represented as = 84
Red = dominant
The homozygous recessive genotype trait is represented as = 16
grey = recessive
2pq = heterozygous individual
Thus for dominant homozygous the alleles are given as
p=
= 9.1
q =
= 4
for heterozygous individual 2pq
2 x 9.1 x 4
= 72.8
72.8% population is heterozygous for the trait.
Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.
