Sperm, Egg (1 egg and 3 polar bodies), 4 different, haploid
Answer:
C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.
Explanation:
The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.
The heterozygous plant Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).
- Dr: parental
- dR: parental
- DR: recombinant
- dr: recombinant
To calculate the frequency of each type of gamete, we must use the formula:
Distance (map units) / 100 = frequency of recombination.
18 mu / 100 = 0.18.
The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.
The frequency of parental gametes will be:
1 - frequency of recombinant gametes
1 - 0.18 = 0.82
But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.

<u>Landslide</u> - <em>According to Microsoft Dictionary, a landslide is the sliding down of a mass of earth or rock from a mountain or cliff.</em>

<u>Lahar</u> - <em>According to Microsoft Dictionary, a lahar is a destructive mudflow on the slopes of a volcano.</em>

<u>Creep</u> - <em>According to Britannica, a creep is a deformation and flow, in physics, alteration in shape or size of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied.</em>

<u>Mudflow</u> - <em>According to Microsoft Dictionary, a mudflow is a fluid or hardened stream or avalanche of mud.</em>

It isn't necessary to stage a play in one's own imagination for one to be able to read the play properly. For that reason, I would say that the answer is False.
Actors don't necessarily carry out plays in their imagination but rather just act it out, so the answer indeed would be false in this case.
