Question: How many types of gametes are found in f2 progeny of cross between AaBbCc and AaBbCc?

How many types of gametes are produced by AaBbCc and AaBbCc?

Hints For Biology 101 Exam #4

No. of homologous chromosome pairs (heterozygous genes) No. of different gametes from each parent
1 (Aa X Aa) 2 (21)
2 (AaBb X AaBb) 4 (22)
3 (AaBbCc X AaBbCc) 8 (23)
4 (AaBbCcDd X AaBbCcDd) 16 (24)

How many offsprings will be formed in the mating between AaBbCc and AaBbCc?

Hint: When two individuals are heterozygous for three different traits, the cross done between them is known as a trihybrid cross. Complete answer: For a trihybrid cross, there are 27 unique genotypic combinations.

How many types of gametes are found in F1 progeny of cross between a BB CC and a BB CC?

So, the number of gametes that will be seen in the F1 progeny = 23= 8.

How many types of gametes are found in f1progeny of cross Aabbccand AaBbCc?

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.

What skin color is Aabbcc?

 Someone who is aabbcc would have very light skin color. If a person who had the AABBCC genotype and a person with the aabbcc genotype had children ..  their children would all be the AaBbCc genotype  and have a ‘mid-brown skin’ phenotype.

How many Gamets will be formed from Ttyyrr?

Since given genotype TtRr is heterozygous for two genes, thus total possible gametes by it = 22=4.

How many kinds of gametes can be formed by the f1 individual?

Thus, maximum number of gametes = 8.
