The Cambrian explosion was a period at the Pre-Cambrian boundary of the geologic time scale at 542 Ma. At this boundary, the fossil record shows that animals suddenly appeared in a dramatic radiation of life. A radiation is the relatively rapid development of new types of organisms that derive from a common ancestor. The Cambrian explosion is important because it marks the origination of all major animal groups called phyla.
i do believe the answer is d for one wheat and other barley products are not made of fats but carbs. and they are really good for energy because it can be broken down alot slower than many other energy sources.. hope this helps.
In the F<span>1 </span>generation of a Mendelian cross,
only the dominant trait is visible.only the recessive trait is visible.neither the dominant nor recessive trait is visible.<span>both the dominant and recessive traits are visible.
-I believe the correct answer is "ONLY THE DOMINANT TRAIT IS VISIBLE" in F1 generation, it is when the two true breeds, both homo (same genes) cross for example, HH and hh, since H will always be present in a punnet square, the answer is ONLY THE DOMINANT TRAIT IS VISIBLE. key word VISIBLE, the dominant trait is H</span>
Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
