Answer:
WILD TYPE= 425;
TAN-BARE= 425;
TAN= 75;
BARE= 75
Explanation:
Fifteen map units apart implies that 15% of the offspring are products of recombination.
Out of 1000 offsprings, therefore 15% of 1000= 0.15 × 1000=150
150 offsprings are products of recombination.
100-15 =85%
Therefore, 85% of the offspring are parental.
So, if tan-bodied, ware-winged female was mated with wild-type male resulting in F1 phenotypically wild-type females were mated to tan-bodied, bare-winged males.
The expected number of offsprings that are tanned but have normal wings would be:
Wild type= 50% of 850
0.50 × 850 = 425
Tan-bare= 50% of 850
0.50 × 850 = 425
tan= 50% of 150
0.50×150= 75
Bare= 50% of 150
0.50×150=75
Explanation:
Primary succession is a type of succession which takes place on the land which is never vegetated in the history of the earth that is barren.
The land could be formed due to volcano eruption, the land formed by the lava flowed from the volcano, land formed due to retreat of the glacier and the new island.
In my community, neither volcano nor glacier retreat can be observed but the "agriculture barren land" can be considered the case of primary succession as it is the only land which is not vegetated.
Peacocks would not be in Hardy-Weinberg Equilibrium
Explanation:
This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.
Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection, mutation, absence of gene flow, and infinite population size.
They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
1. The answer is "<span>the energy required to start the reaction".
</span>This energy is called as activation energy of the reaction. If the activation
energy is high, reaction is slow. Enzymes help to carry out the reaction by
a new path by reducing the activation energy. But the energy of reactants
and the products remain as same as without enzyme.
2. The answer is "reaction in cells would be too slow to sustain life<span>".
</span>If the activation energy is very high for the reaction, then that reaction will
be very slow and will require more time<span> to complete the reaction. Then survival is
very low. Hence, the roll of enzymes is very important to sustain life.</span>
The relationship between chromosomes, genes and alleles is D. A specific part of the chromosome is a gene, and the alleles are different variations of the genes.
