Heterozygous traits
Polygenic traits
Sex-linked traits

Answer 2

A number of human traits are the result of 2 types of alleles that are equally dominant. Such traits are said to be codominant for that trait. When an individual is heterozygous for such traits, the resulting phenotype or expression of these two traits is a blending, because both traits are expressed equally.

Answer 3

Any time an individual has two different alleles for a gene, the individual's genotype is heterozygous. For genes with simple dominance, like the pea example, the dominant allele is always expressed, so heterozgyous individuals have the dominant trait

Answer 4

Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.

can you help with one more?

Answer 6

This is why males exhibit some traits more frequently than females. In humans, red-green colorblindness is a recessive sex-linked trait. It is found on the X chromosome, not the Y. Because, males only have one X chromosome, they have a much greater chance of having red-green colorblindness.

Answer 7

Sure :)

Answer 8

Which of the following technologies would best help a dairy farmer who wants to have large cows that produce more milk?

Artificial selection, because the offspring produced would have the desired traits
Genetic engineering, because it helps increase the diversity of animals by making them stronger
Genetic engineering, because there are confirmed long-term health benefits of consuming GMO
Artificial selection, because it increases the variation in a certain species by creating healthier organisms

Answer 9

I feel like this would be option 2 or "b"
