My mom was average height and my dad was short and mine short. I am think my genotype is heterozgous.

My mom weight is average and my dad was overweight and my was average. I am think my genotype is homozygous.

To determine your genotype for height and weight, you need to understand how these traits are inherited. Height and weight can be influenced by multiple genes and environmental factors, but for the purpose of this example, let's simplify it to one gene each.

For height:
- Height is a polygenic trait, which means it is influenced by multiple genes.
- However, we'll consider a single gene with two alleles: "T" for tall and "t" for short.
- If your mom was of average height and your dad was short, it's possible that they both had the genotype "Tt".
- As their child, you could inherit either the "T" allele from your mom or the "t" allele from your dad.
- Since you have short height, it suggests that you inherited the "t" allele from your dad.
- Therefore, your genotype for height could be "tt", which would make you homozygous for the short trait.

For weight:
- Weight can also be influenced by multiple genes and environmental factors, but let's consider a single gene with two alleles: "A" for average weight and "O" for overweight.
- If your mom had average weight and your dad was overweight, it's possible that they had the genotypes "AO" (mom) and "OO" (dad).
- As their child, you could inherit either the "A" allele from your mom or the "O" allele from your dad.
- Since you have average weight, it suggests that you inherited the "A" allele from your mom.
- Therefore, your genotype for weight could be "AO", which would make you heterozygous for the weight trait.

In summary:
- Your genotype for height could be "tt", making you homozygous for the short trait.
- Your genotype for weight could be "AO", making you heterozygous for the weight trait.
