Two different gametes, i.e. the male and female gametes are required in order to reproduce sexually. Different gametes bear different genetic information that comes from male and female separately. When the two gametes unite, they bring about variations in the progeny.
How many different types of gametes can be formed by individuals of the 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 different types of gametes could be produced by an individual with the arbitrary genotype of AAbbccddEE?
The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).
How many gametes can be produced from 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)|
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.
How many unique gametes can be produced?
How many unique gametes could be produced through independent assortment by an individual with genotype – AaBbCCDdEE? The answer is eight. 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).
What is an example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
