Answer:
1 .tall (or heterozygous)
2. 3:1
3. carriers
4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half.
5. Therefore, each gamete contributes only one allele. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.
6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.
7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.

Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase<span>. The sporophyte phase produces spores by meiosis within a sporangium. The </span>gametophyte phase<span> produces gametes by mitosis within an antheridium (producing sperm) and/or archegonium (producing eggs).</span>

Hope this helps :))
Basically, this chorion tissue is made of the chorionic villi and this functions by providing maximum contact area with the blood of the mother. So in case this tissue ruptures, what happens is that the maternal tissue of the placenta would be damaged and this may result in bleeding. Hope this helps.
