Additional information is missing. It is as follows: In fruit flies, the allele for red eyes is dominant over the allele for pink eyes. Straight wings are dominant over curled wings.
Answer:
Genotype = RrSS and RrSs in 1:1 ratio so each has 0.5 probability
Phenotype = All red eyed and straight winged
Explanation:
Given,
Red eyes (R) is dominant over pink eyes (r)
Straight wings (S) is dominant over curled wings (s)
Fly 1 : Homozygous red eyed, curly winged = RRss
Fly 2 : Pink eyed, heterozygous straight winged = rrSs
RRss will produce Rs gametes and rrSs will produce rS and rs gamates.
When fly 1 and fly 2 mate : RRss X rrSs :
rS rs
RS RrSS RrSs
The genotypic ratio is 1 : 1 ( RrSS : RrSs ) that means that each genotype has 0.5 probability. Both the genotypes though have at least one dominant allele for each gene so the entire progeny will have red eyes and straight wings.
Answer;In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
Explanation:
The answer is pink will be the color
The answer to this is A because groups of cells do form tissues.
Answer:
The correct answer is d. provide structural support and nutrition to the neuron.
Explanation:
Glial cells are the cells that surround the neurons and provide structural support to them. They also help in insulation for neurons. They are the most abundant cells present in the nervous system.
Many glial cell plays a role in providing nutrition and oxygen to the neurons and regulation of extracellular brain fluid. Glial cells also helps in cleaning up the dead neurons.
The different types of glial cells are ependymal cells, schwann cells, microglia, oligodendrocytes, astrocytes, and satellite cells. So the right answer is d.
