The man could have either free hanging or attached earlobes. His possible genotypes could be either homozygous for free hanging earlobes (LL) or heterozygous for free hanging and attached earlobes (Ll).
For a plant with green seeds, the possible genotypes depend on whether green seed color is dominant or recessive. If green is dominant (G), the genotypes could be homozygous dominant (GG) or heterozygous (Gg). If green is recessive (g), the only genotype would be homozygous recessive (gg). Therefore, the possible genotypes for green seeds are GG or Gg, assuming green is dominant.
The genotype of the offspring with yellow pods is likely homozygous dominant (YY) or heterozygous (Yy), assuming yellow pods are dominant over green. The possible genotypes of the offspring with green pods would be homozygous recessive (yy), as green is the recessive trait. If both yellow-podded parents are heterozygous (Yy), some offspring could also be yellow (YY or Yy) while others could be green (yy).

Yes - Hh is heterozygous. HH is homozygous, and hh is homozygous.

Is tall dominant? You didn't say. Let's assume it is. Therefore, as long as a dominant allele is one of the two alleles an organism has for every trait, and we let "R" stand for dominant tall and 'r' stand for recessive short, then either an RR or Rr genotype will result in a tall phenotype.

In a pedigree where curly hair (C) is a dominant trait, the genotypes of the parents can vary. If at least one parent has curly hair, their genotype could be either CC (homozygous dominant) or Cc (heterozygous). If both parents have straight hair (which is the recessive trait), their genotype must be cc. To determine the specific genotypes of the parents more accurately, you would need to analyze the phenotypes of their offspring in the pedigree.
The expected genotypic ratio differs from the expected phenotypic ratio because genotypes represent the actual genetic combinations (e.g., homozygous dominant, heterozygous, homozygous recessive), while phenotypes reflect the observable traits resulting from those genotypes. In cases where one allele is dominant over another, multiple genotypes can lead to the same phenotype. For example, in a monohybrid cross, the expected genotypic ratio might be 1:2:1 for the alleles, while the phenotypic ratio could be 3:1, as both homozygous dominant and heterozygous individuals display the same dominant phenotype.
The likely genotypes of the squash plants that were crossed would depend on the specific traits being studied. If looking at a single trait with two alleles (e.g., round vs. wrinkled fruit shape), the genotypes could be homozygous dominant (RR), heterozygous (Rr), or homozygous recessive (rr). For multiple traits or genes, the genotypes would involve combinations of alleles for each trait.
both parents could be A heterozygous or one A heterozygous and the other O
