Answer: d. know the father's genotype
Explanation: Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype.
Answer:
Organism in a lichen that provides protection - algae
Organism in a lichen that provides nutrients through photosynthesis - algae
Branched growth form of lichen - fruticose
Leafy growth form of lichen - foliose
Small and flat growth form of lichen - crustose
Explanation:
<em>Lichens are composite organisms that are formed from symbiotic relationships between fungi and cyanobacteria/algae. The Green algae layer offers food to the fungi by photosynthesis while the latter supplies nutrients and offers protection to the algal component. </em>
There are different types of lichen based on the growth structure:
Fruticose lichens grow upright and shrubby and posses either round or flat branches.
Foliose lichen appears like a leaf with upper and lower layers. They are usually flat or convoluted in nature.
Crustose lichens are small in appearance with flat, crusty growth on surfaces on which they grow.
Answer:
Frequency of the B3 allele 
Explanation:
The allele frequencies in a given population remain constant which means that every generation will have the same gene pool across the generations. As per Hardy Weinberg’s first equilibrium equation, the sum of frequency of all the alleles at a given locus is equal to one
Thus, if "p" represents the frequency of B1 allele and "q" represents the frequency of B2 allele and "r" represents the allele for B3 allele. Then, sum or "p", "q" and "r" is equal to one.

Substituting the given values, we get -

Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
