How many kinds of genotypes will the offspring have?

Figure 13: The possible genotypes for each of the four phenotypes. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.

How many genotypes are possible for the offspring?

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. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33.

How many genotypes are there?

A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes?

Can there be 4 genotypes?

However, a fly that has a normal body color may have the homozygous genotype EE or the heterozygous genotype Ee. Things get slightly more complex when considering two genes. For instance, a wild-type fly (with red eyes and a yellow body) has one of four possible genotypes: EEBB, EEBb, EeBB, and EeBb.

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.

What is the percentage of an offspring?

Divide the number of boxes with a dominant allele by four and multiply the result by 100 to get the percent chance that an offspring will have the dominant trait. For example (2/4)*100 = 50, so there is a 50 percent chance of an offspring having brown eyes.

When the offspring inherit the father’s name the family is called?

As the offspring of a new species, also known as a child or f1 generation, consist of genes of the father and the mother, which is also known as the parent generation.

Can As marry AA?

It is safe for someone with AS to marry someone with AA genotype. Two sickle cells should not even have a relationship or get married. Individuals with the AA genotype should help you prevent genetic abnormalities by marrying the AS, AC, and SS. Compatible genotypes for marriage are: AA marries an AS.
