Answer:
The reason is because the moon's orbit about the earth is about 5 degrees off from the earth-sun orbital plane. However, at special times during the year, the earth, moon, and sun do in fact "line up". When the moon blocks the sun or a part of it, it's called a solar eclipse, and it can only happen during the new moon phase.

Answer: Sysy × Sysy i.e. <em>all are genotypically heterozygous, inflated, and yellow</em>
Explanation:
Punnett squares are a diagrammatic means of determining traits of hybrid offspring produced via crosses in genetic breeding. The parental genotypes and phenotypes are usually known, and these typically follow standard Mendelian ratios and inheritance.
Mendelian genetics focus on trait inheritance, or heritability. These traits are packaged out into its own gamete, inherited by themselves and often show dominance, where one's effect may mask those of another trait.
These are called the Law of Segregation, Independent assortment and Dominance respectively.
For this cross...
Parent generation or P generation:
gametes: Y → pod color green dominant (Y), yellow recessive (y)
S→ pod size; inflated dominant (S), constricted recessive (c)
Assumptions...
- True breeding plants are homozygous, with identical sets of alleles
- The other parent is heterozygous, as it was not said to breed true
P generation: SySy × sysy
<em> yellow, inflated </em>× <em> yellow, constricted</em>
<em></em>
F1 generation: Sysy × Sysy ...(from punnet square)
<em>phenotype</em><em>: yellow, inflated </em>× <em> yellow, inflated </em>
<em></em>
<em>∴ all are genotypically heterozygous, inflated, and yellow</em>
