The answer is a pedigree chart.
<span>Pedigree charts are used to explain the occurrence of particular genes from one generation to the next. It gives enough information about family disease history. They are used in families to find out the probability of inheriting some disease. So, if Maria and Juanita are cousins and the genotypes of other members of their family are known, the pedigree chart could predict their genotypes. Still, it is not as precisely as DNA test.</span>
Answer:
Decrease
Explanation:
sorry if it's not one of the choices
Channel proteins that form a narrow passageway in gap junctions are known as <span>connexons
</span><span>Connexons are assemblies of six proteins that form a pore or a narrow passageway between the cytoplasm of two adjacent cells.
These passageways allow the bidirectional passage of iron and signals between the cells. </span>

Eukaryotic because it is found in plants and animals and not single celles
Answer:
B) 300
Explanation:
There are two types of alleles present for wing type in this population of Drosophila, c and c+. Various combinations of these two alleles will produce different phenotypes.
c+c+ : straight wings = 45
c+c: straight wings = 70
cc: curly wings = 35
Total flies = 150
Each fly has one gene with two alleles for wing type. Hence 150 flies will have 300 alleles in the gene pool.
