Question: What is the genotype of the Brown parent?

What is the genotype for brown?

B, for brown hair, is a dominant allele. This means than someone who has a genotype of “BB” or “Bb” will have brown hair. In other words, that person’s phenotype will be that they have brown hair. Recessive alleles are represented with lowercase letters.

What is the genotype of the parents?

Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype. Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype.

What is the genotype of the white parent?

Since there are recessive offspring, the white parent must have carried the recessive allele and therefore had the heterozygous genotype, Ww. … Since there are F1 offspring that are homozygous recessive for both traits, the white-disk parent must have carried the recessive allele for each trait.

Is brown a genotype or phenotype?

Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.

What is my genotype?

In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. 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.

What are the 3 types of genotypes?

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

Is the genotype DD?

Background: The DD genotype gene is a linkage marker for an etiologic mutation at or near the angiotensin-converting enzyme gene and has been associated with increased risk for the development of coronary artery disease, left ventricular hypertrophy and left ventricular dilation after myocardial infarction.

Is AA heterozygous or homozygous?

If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.
