Describe what happens during prophase I and metaphase I and how these phases play an important role in the genetic diversity of

the daughter cells produced
Biology

vivado [14]3 years ago
7 0

In prophase, DNA begins to cluster. In metaphase, two identical, condensed DNA strands line themselves up in the middle of the cell. After metaphase, there are: Anaphase, Telophase, and Cytokinesis. This process excluding or including Cytokinesis is called mitosis.

In the DNA replication for a cell baby, meiosis occurs.

What similarities in flower structure are found among the plants in the rose family
emmainna [20.7K]

The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic.  Rosaceae generally have five sepals, and five petals. They also have many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a  cup-like structure called a hypanthium. They can be arranged in racemes, spikes, or heads; solitary flowers are rare.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats
marta [7]

Answer:

0.1 x 0.3 = 0.03 = 3%

Explanation:

Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations).  In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.
