b) Assume that Ay is a dominant allele that codes for purple leaves and A2 is a recessive allele that
codes for white leaves. What will be the frequencies of purple and white phenotypes in this population?
Answer:
All plants of purple colour.
Explanation:
All the offspring plants of F1 generation have purple leaves because Ay is dominant allele which appear in the leaf colour instead of A2 which is a recessive allele. In the F1 generation, the dominant allele must appear in the shape and structure of the offspring whereas the recessive allele does not appear so offspring of purple leaves appear if plants have purple leaves cross with white leaves.
When the nursery at the hospital caught on fire, everybody rushed out with a baby. Unfortunately, after the fire was put out, the babies were in the wrong cribs. Fortunately, the hospital could type all the babies blood types.
Baby#1 was type O
Baby#2 was type B
Baby#3 was type AB.
1. Mr and Mrs jones both had type A blood. Which baby was theirs?
2. Mr and Mrs Williams had types AB and O blood. Which baby was theirs?
3. Mr and Mrs Wilson had types B and A blood. Which baby was theirs?
Answer:
baby #1 goes to family 2
baby #3 goes to family 1
and baby #2 goes to family 3
Explanation:
its simpler then it looks☺
Baby with blood group O belongs to Mr. and Mrs. Jones, baby with blood group B belongs to Mr. and Mrs. Williams, and baby with blood group AB belongs to Mr. and Mrs. Wilson.
What is a blood group?
Blood group or blood type is the classification of the blood cells into different classes on the basis of presence or absence of antibodies and antigens on the membrane of the blood cells.
The alleles which can be formed in case of Mr. and Mrs. Jones are AA or Ai type. These alleles can only result into formation of an offspring with blood group O or A. Similarly, the possible combination of alleles in case of Mr. and Mrs. Williams is AB and ii, these combinations will result into development of offspring with blood group A or B. In case of Mr. and Mrs. Wilson, the possible combinations of alleles are Ai or AA and Bi or BB, which results into formation of offspring with blood group AB.
This can also be represented through punnett square.

A disaster wipes out 50 percent of a small population of birds. Prior to the disaster, about half the birds had a green wing patch and half had a blue wing patch. Several generations after the disaster, only 10 percent have a blue wing patch, and 90 percent have a green wing patch. What do you infer happened, and why?
Answer:
The correct answer is - genetic drift takes place due to disaster in favor of a green wing patch.
Explanation:
In this given scenario there is disaster happened that wiped out 50% of a population of birds in which half had green wings and the rest half had blue wing birds before the catastrophe.
Due to this sudden catastrophe, the genetic drift occurred and also reduced the population to half and the ratio of both types of birds changed and favored the green wings as they are better adapted for the new conditions.
4. Which material dissolves
most substances in chemical
weathering?
Answer:

B) Ciliates ate the only species that contain cilia. C) Ciliates and fungi diverged more recently than ciliates and flagellates. D) Ciliates are more closely related to animals than they are to flagellates. E) Slime molds and ciliates have more common features than slime molds and fungi.
Answer:
C and D
Explanation:

Ciliates and fungi diverged more recently than ciliates and flagellates and Ciliates are more closely related to animals than they are to flagellates shows hypothetical model of the relationships between groups of organisms.
What is hypothetical model?Hypothetical modeling involves the design and analysis of basic hypothetical systems to represent complicated social phenomena for the purpose of understanding those social phenomena.
Hypothetical modeling is contrasted with both computer simulation and lab experiments to emphasize its key characteristics.
In analogy with laboratory experiments, hypothetical models can be viewed of as scientific representations that aim to isolate, hypothetically, the working of causal mechanisms or capacities from disrupting influences.

Explain how errors in DNA replication and environmental factors cause genétic variation
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer.
