How many genotypes can each trait have?

How many genotypes can each trait have?

When the gene for one trait exists as only two alleles & the alleles play according to Mendel’s Law of Dominance, there are 3 possible genotypes (combination of alleles) & 2 possible phenotypes (the dominant one or the recessive one).

How many phenotypes do single gene traits have?

How many possible genotypes and phenotypes are there for a single-gene trait that shows dominance? Answer Expert Verified The answer is C. Three genotypes, two phenotypes. This is because of the dominance of A allele over a allele.

How many alleles does a single gene trait have?

two alleles
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.

How many genotypes can 3 genes have?

For three gene pairs, there are 33 , or 27, possible genotypes.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

Is red hair a phenotype?

Red hair is the null phenotype of MC1R.

Is height a single gene trait?

Height and other similar features are controlled not just by one gene, but rather, by multiple (often many) genes that each make a small contribution to the overall outcome. This inheritance pattern is sometimes called polygenic inheritance (poly- = many).

Can a single gene control a single trait?

A single gene can control a single trait. A single trait can be controlled by multiple genes.

Can a single gene can control a single trait?

Can AA and AA get married?

Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible. That way you save your future children the worry about genotype compatibility.

Is AA a genotype?

What is a Genotype? There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.

Why do redheads have yellow teeth?

We’ve been talking about how most natural redheads have very fair, translucent skin. In turn, this means thinner teeth enamel and yellow-looking teeth.
