How many skin colors would there be if it was inherited in a simple recessive pattern rather than in a polygenic fashion?

How many skin colors would there be if it was inherited in a simple recessive pattern rather than in a polygenic fashion?

How many skin colors would there be if it was inherited in a simple recessive pattern rather than in a polygenetic fashion? At least four.

How many forms of a gene are there per gene?

two alleles
Individual humans have two alleles, or versions, of every gene. Because humans have two gene variants for each gene, we are known as diploid organisms. The greater the number of potential alleles, the more diversity in a given heritable trait.

What are the names of the 3 genotypes that an individual can have?

Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa.

Why are there more than 7 shades of skin color?

there are more than 7 shades of skin color. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.

What different forms of a gene are called?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Which is the gene responsible for the hair color?

For example, the gene responsible for the hair color trait has many alleles: an allele for brown hair, an allele for blonde hair, an allele for red hair, and so on.

How many copies of each gene do humans have?

Humans have two copies (or alleles) of each gene, one inherited from each parent. Alleles play a significant role in shaping each human’s individual features. Alleles are versions of the same gene with slight variations in their sequence of DNA bases.

How many genes are needed to determine a trait?

Genes determine your traits, like how tall you are, what color your eyes are, and what color your hair is. But a single trait is usually determined by a number of genes, rather than just one. For example, height alone is determined by over 400 genes. Humans and other multicellular organisms have two alleles at the same site on a chromosome.

What makes up the spectrum of human skin color?

Extended Coloured family from South Africa showing some spectrum of human skin coloration. Human skin color ranges in variety from the darkest brown to the lightest hues. An individual’s skin pigmentation is the result of genetics, being the product of both of the individual’s biological parents’ genetic makeup, and exposure to sun.
