I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)
RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.
For Rryy :
Rr is heterozygous (the alleles are not the same), so the parents could be:
RR x rr
RR x Rr
Rr x Rr
(if you do a small punnet square, you can double check these!)
Since yy has both recessive alleles, the parent is yy as well.
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
Answer:
1. Mutation
2. Gene flow
Explanation:
New traits can be made when there is an error in gene replication, called a mutation. The mutation will give the offspring different genes that might be harmful or beneficial to the organism.
Gene flow happens when any organisms from other places immigrate into the population. If these organisms can reproduce with the local organisms, it will introduce new traits that was not originally come from the population.
One way that bacteria and archaea is in the structure of the cell membranes.
The heat of vaporization refers to the amount of energy necessary to add to a substance in order to convert the substance from liquid to gas. Water has a high heat of vaporization measuring 40.65 kJ/mol. This means that a lot of energy must be put into it before it evaporates. As a result, humans are able to maintain their body temperature since the human body is mostly made up of water. Moreover, it keeps the Earth's climate at a steady temperature as well. Thus, living organisms are able to live in an environment that does not rapidly change in temperature as a result of changes in their immediate surroundings.
