What allele combinations are present in the gametes?
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
What are all possible gametes that can be produced by an individual with the genotype FFGg?
Answer: All possible gametes are FG and Fg. Explanation: The individual in a given question has genotype FFGg.
What is the combination of alleles for a trait?
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
How do you find gamete combinations?
If you know the haploid number for an organism, you can calculate the number of possible combinations in the gametes. The possible combinations are equal to 2n, where n is the haploid number. For the organism in Figure 9-18, n = 2, so the number of chromosome combinations is 22, or 4.
How many gametes can be formed from Aabbccdd?
One type by AABBCCDD & 16 type by individual Aa Bb Cc Dd 24 = 16.
How many different genotypes are there?
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.
What is a genotype simple definition?
Genotype: The genetic constitution (genome) of a cell, an individual, or an organism. The genotype is distinct from the expressed features, or phenotype, of the cell, individual, or organism. The genotype of a person is that person’s genetic makeup. It can pertain to all genes or to a specific gene.
What is genotype as all about?
A genotype is the entire genetic constitution of an individual, i.e. the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
What is a phenotype percentage?
A phenotypic percenage is a comparison of the number of each phenotype that is expressed in the offspring.
