How many different phenotypes are possible in the offspring?

How many different phenotypes are possible in the offspring quizlet?

With two alleles for a trait, up to three phenotypes are possible. With three alleles, up to six phenotypes are possible.

How many phenotypes that would possible come out?

There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.

What are 3 possible phenotypes?

If the only alleles for hair texture were straight and curly, there would be three phenotypes: straight, curly, and wavy. However, you asked for something a little different. You wanted three phenotypes that are all equally represented in the population.

How many different phenotypes are possible for offspring?

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 different genotypes are possible among 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. First we must appreciate that genes do not act in isolation.

IT IS INTERESTING:  Question: Why is phenotypic variation important?

How do you determine the genotype and phenotype?

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.

What are the 3 types of genotypes?

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

What is the phenotype of AA?

One allele is usually dominant. … The other allele is usually recessive which means it is only expressed if there are no alternate forms of the gene (other alleles) present. Therefore, both the genotypes AA and Aa produce a red feather phenotype.
