Answer:
OS, Os, oS, os
Explanation:
To do this, first we need to determine what the genotype of the Plant C offspring is. Since the parents are both true bred, this means that their offspring will get one allele of each parent, of each trait.
Here's a Punnett to help you there
OOSS x ooss
os os os os
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
So Plant C would have a genotype of OoSs.
A good trick to determining the gametes of a dihybrid, is the FOIL method. Just like in math, F- first, O-outside, I- inside, and L-Last
Look at the attachment to see the FOIL method:
Answer:
atp means adenosine tri phosphate
Explanation:
and ADP means adenosine do phosphate
<span>For the answer to the question above,
DD <-- all (homozygous) dominant
dd <--- all (homozygous) recessive
DD-X dd
__d__d
D Dd Dd
D Dd Dd
^your Punnett square
since there is a dominant gene in Dd, Dd's phenotype will be of the dominant. Therefore, an all dominant allele X an all recessive allele will yield an all dominant phenotype offspring.</span>
Directional selection increases the frequency of individuals expressing one of the extreme phenotypic traits in a population. At some time in history, directional selection led to the Warbler-finches evolution.
<h3>
What is Directional Selection?</h3>
Directional selection is one of the different types of natural selection.
It increases in the proportion of individuals with an extreme phenotypic trait.
It causes a decrease in the number of individuals expressing intermediate phenotype, and the other extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example,
- All finches vary from 10 to 20 cm, but Warbler-finches is closer to 10 cm (one of the phenotypic extremes).
- All finches vary from 8 to 38 g, but Warbler-finches is closer to 8g (one of the phenotypic extremes).
So, from the whole range, Warbler-finches only express one of the extreme traits, meaning that the species has suffered from the directional selection.
These traits probably increased the animals' fitness, and hence, they were favored by natural selection.
