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).
How many gametes can AA produce?
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 is an organism with the genotype AA?
The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
Is AA a haploid or diploid?
The two alleles make the genotype for a particular trait. The genotype options are: AA, Aa, or aa. However, in haploid organisms, there is no mother and father, but instead there is only a single parent cell (because haploid organisms reproduce asexually).
Which gametes can the Aa Bb parent generate?
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 different kinds of gametes will be produced by a plant having the genotype Aa Bb Cc?
Explanation: A plant having genotype AABbCC will produce only two types of gametes, ABC and AbC.
What gametes can be produced from an individual with the genotype 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).
Which is a possible genotype for a gamete produced by an organism with the genotype AABbCc?
These types of genotypes that are ABC, ABc, AbC, and Abc will be found in the gametes. Thus the number of gametes produced by the plant having the genotype AABbCc is four.
How many types of gametes are produced by the individual with genotype Aabbccdd and Aabbccdd?
One type by AABBCCDD & 16 type by individual Aa Bb Cc Dd (24 = 16).
What is the meaning of AA AS and SS genotype?
Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA, AS, AC, SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.
What is the probability that an AA individual will produce a gamete with an A allele?
The only way to get an aa individual is if the mother contributes an a gamete and the father contributes an a gamete. Each parent has a 1 / 2 1/2 1/2 chance of making an a gamete.
How many gametes are formed in Aabbccdd?
One type by AABBCCDD & 16 type by individual Aa Bb Cc Dd 24 = 16.
What is the difference between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
