Answer:
The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.
Explanation:
The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.
Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.
<span>C. Gametes are the sex cells, and each (sperm and ovum) contain half of the parent's genetic material. These cells will fuse to produce a zygote, which will usually contain the full number of genes required by an organism to live. If there is a chromosomal abnormality, such as a gamete with an extra chromosome, the offspring can either die in development or sometimes be born with physiological and/or developmental difficulties. An example of this phenomenon is trisomy 21, also known as Down Syndrome, in which the 21st chromosome bears 3 copies instead of the regular 2.</span>
Answer:The answer is option A sister chromatids are separated from each other to form gametes.
Explanation:
Meiosis is a type of cell division which produces 4 daughter cells with different genetic material. The ploidy number or set of chromosomes is reduced to half in the newly formed daughter cells.This process usually proceeds in two divisions-meiosis I and meiosis II with four stages in each division which are prophase, metaphase, anaphase and telophase.Sister chromatids separate from each other during anaphase II of meiosis II which produces four haploid gametes from two intermediate cells formed by meiosis I.Thus, sister chromatids are separated from each other to form gametes is the correct answer.
They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves.
Answer:
Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). Generally speaking, height, density, and species diversity decreases from warm, wet climates to cool, dry climates. Raunkiaer (1934) classified plant life forms based on traits that varied with climate.
