<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.

3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>
Answer:
Pseudopodia. (Ans A)
Explanation:
Pseudopodia are defined as the projections of the cytoplasm of the eukaryotic cell membrane, and unicellular protists. They are synthesized by the microtubules, and filament structures. They are divided into different shapes, and types such as: Lobopodia, Filopodia, Reticulopodia, and Axopodia.
Axopodia pseudopods are supported by microtubules array, they are covered by the cytoplasm, and mostly used for catch and ingestion of food. Genus Heliozoa, and Radiolaria of protists are example of Axopodia pseudopods.
D.
A fixed allele is homozygous within a population so D should be the correct answer.
Hope this helps!
Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.
