What type of genotype is AaBbCc?
The plant having genotype AABbCC is heterozygous for only one character B. Number of “gametes = 2n”, where n is the heterozygosity.” Since n = 1 so 2 gametes will be formed. Those are ABC and AbC. So the two types of gametes will be ABC and AbC.
How many genes are in the genotype AaBbCc?
Hints For Biology 101 Exam #4
|No. of homologous chromosome pairs (heterozygous genes)||No. of different gametes from each parent|
|3 (AaBbCc X AaBbCc)||8 (23)|
|4 (AaBbCcDd X AaBbCcDd)||16 (24)|
|20 pairs of chromosomes||1,048,576 (220)|
|23 pairs of chromosomes||8,388,608 (223)|
How many phenotypes are possible AaBbCc?
In the above crossAaBbCc×AaBbCc, there are three pairs of characters which are Aa, Bb, Cc. Therefore, the number of possible phenotypes are 23=8. Hence, the correct option is C. 8.
What is wild type phenotype?
: a phenotype, genotype, or gene that predominates in a natural population of organisms or strain of organisms in contrast to that of natural or laboratory mutant forms also : an organism or strain displaying the wild type.
How do you calculate genotypes?
Number of genotypes for a given number of alleles Given n alleles at a locus, the number genotypes possible is the sum of the integers between 1 and n: With 2 alleles, the number of genotypes is 1 + 2 = 3. 3 alleles there are 1 + 2 + 3 = 6 genotypes. 4 alleles there are 1 + 2 + 3 + 4 = 10 genotypes.
What frequency is AaBbCc?
Hence the genome of the spring should be AaBbCc regarding three genes. So the offspring has a combination of homozygous and heterozygous. Hence the offspring genotype is Aa and AA which is heterozygous and homozygous so that frequency will be 12and 12. Hence, the frequency of Aa is 12.
How many offsprings will be formed in the mating between AaBbCc * AaBbCc?
Mating between the genotypes AAbbCCDd x AaBbCcdd produces 16 different types of offsprings. Types of gametes formed are determined by 2ⁿ where n stands for degree of heterozygosity.
How many phenotypes are possible?
A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.
