In the sentence "The F2 generation phenotypes resulting from the
monohybrid cross of purebreds display a ratio of _____" the word that
correctly completes the sentence is 3:1. In the monohybrid cross of
purebreds, F1 generation will consist of heterozygotes with dominant
phenotype. When F1 generation cross, the F2 generation phenotypes will
be as following: 3 dominant phenotypes (1 dominant homozygote and 2
heterozygotes) and 1 recessive phenotype (1 recessive homozygote).

The Sidereal Day is 4 minutes shorter than the Mean Solar Day, because the rotation of the Earth on its axis, and the orbiting of the Earth around the Sun, are both counterclockwise, as viewed from above (or north of) the Ecliptic Plane. See planetary retrograde motion for an example of the opposite situation.
The reason that the Solar Day varies around the Mean Solar Day is that the Earth moves at different speeds through its orbit around the Sun. This is in keeping with Kepler's Second Law of Planetary Motion.
Please note that the Mean Solar Day changes over a long period of time, due to the slowing of the rotation of the Earth due to tidal forces exerted on the Earth primarily by the Moon. For example, the Mean Solar Day was about 23 hours about 250 million years ago.
Overproduction - An organism gives birth to too many children
Genetic Variation - The offspring each have genetic differences in appearance, behavior, etc
Struggle to Survive - Offspring must fight in order to gain essential resources (food, water, mates, etc)
Successful Reproduction - Organism produces offspring with beneficial adaptations that aid in survival
Answer:
The % of children with webbed digits is %
Explanation:
Given -
Syndactyly or webbed digits are due to the presence of a dominant allele (S). Then the allele for normal digits would be represented by allele "s"
A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"
If we cross Ss and ss , then the following offspring are produced -
Ss * ss
Ss, Ss, ss, ss
Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is %
