8 gametes will be formed by F1 progeny, from the following cross.
How many types of gametes are found in F1 progeny of cross Aa Bb Cc and Aa Bb Cc *?
A cross between AABBCC and aabbcc genotypes produces F1 hybrid with AaBbCc genotype. Total number of types of gamete produce by an organism is 2n, where n is the number of heterozygous genes present. The hybrid AaBbCc is heterozygous for three genes, thus total possible gametes by it = 23=8.
How many types of gametes are formed in F1 generation?
So, the correct option is ‘8‘.
How many types of gamete are produced by AA BB CC genotype?
The number of gametes produced by a specific genotype is calculated by the formula 2n, where n= number of heterogeneous alleles present in the genotype. Here, the given genotype consists of two heterogeneous alleles Aa and Bb while CC is homozygous. So, it can produce 22 = 4 types of gametes.
How many gametes are formed in Dihybrid cross?
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.
How many gametes are formed in F1 of Dihybrid?
➢Each dihybrid plant produces 4 gamete types of equal frequency. in the offspring.
What are the gametes that would be formed for the following genotype AA?
A heterozygous individual has two different alleles. Therefore it would have the genotype Aa. 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.
