How many gametes are produced by genotypes aabbccddee?
So number f gametes will be n^3 or 8. So a number of different gametes produced by genotypes AABbCCDdEe will be 8. In this case you have to look for the number of heterozygous loci which are :Bb,Dd,Ee i.e 3 in number. Next we apply the formula for number of gametes=2^n,where n=No. of heterozygous loci Hope you understood the approach.
How many gametes can a homozygous individual produce?
Eliminate the Cs and the Es — since the individual is homozygous at those loci, they can only produce one kind of gamete (with a C and an E). The other three — the As, Bs, and Ds, can produce two at each locus (A and a, B and b, D and d).
How do you determine the genotype of offspring from gametes?
Predicting the genotype of offspring 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 the dominant and recessive alleles in gametes?
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.
How many gametes will be formed from AABBCCDDee?
So, the correct answer is 'Two'.
What is the probability that any of the offspring will have the genotype AABBCCDDee?
What is the probability that any offspring will have the genotype AABBCCDDee? Justify your answer. Because one of the parents is dd at the D locus, the offspring can't have the DD genotype at that locus, so the probability is 0.
How many types of gametes does the person with AABbCC genotype produce?
∙ Hence, 4 types of gametes are formed from the genotype AABbCc.
How do you calculate the number of gametes?

How many different gametes can be produced by an individual with the genotype?
An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete. (Frequency of 1/2 for each gamete). A second individual with genotype Aa can make two types of gametes: A and a.
What is the genotype of AaBbCc?
The plant having the genotype AaBbCc is a triploid plant. To calculate the total number of gametes that are produced by a particular genotype, a specific formula 2n is used, where n= number of heterogeneous alleles that are found in the genotype.
How many types of gametes is being formed from YyRr genotype?
two different genotype gametesYR and yR are two different genotype gametes may be formed from this genotype.
How many types of gametes can be produced by YyRr?
After fertilisation, the F1 heterozygote will be formed i.e YyRr (yellow and round). On selfing F1 we get two possible combinations i.e YR, Yr, yR, yr. Therefore four types of gametes are formed in the ratio of 1:1:1:1. Thus, the correct answer is option D.
