A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules. What is genotype with example? Genotype examples ARead More →
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. Can AA blood group marry? Blood type has no effect on your ability to have and maintain a happy, healthy marriage. There areRead More →
Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus). What are the 3 types of genotypes? There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous. What is the genotype of the heterozygote? The presence of two different alleles at aRead More →
For the mutant phenotype to occur, both alleles must carry the mutation. Dominant mutations lead to a mutant phenotype in the presence of a normal copy of the gene. The phenotypes associated with dominant mutations may represent either a loss or a gain of function. Why mutation does not affectRead More →
Heterozygous Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent. What happens if both parents are heterozygous? If both parents are heterozygousRead More →
Simply place a 2 above each heterozygous gene pair and a one above each homozygous gene pair. Then multiply the numbers together to obtain the total number of different possible gametes. Is AaBb a genotype or phenotype? The individual with genotype recessive for both traits, i.e. aabb, has the sameRead More →
The probability that one of their offspring will have white flowers is 1/4 . When crossing purple flower plants Why would some of the offspring have white flowers? The second generation had a 3:1 ratio of purple:white because when the offspring (F1 generation) reproduced they had the recessive white geneRead More →
Genotype: The genetic constitution (genome) of a cell, an individual, or an organism. The genotype is distinct from the expressed features, or phenotype, of the cell, individual, or organism. The genotype of a person is that person’s genetic makeup. It can pertain to all genes or to a specific gene.Read More →
If an individual inherits two identical alleles, their genotype is said to be homozygous at that locus. However, if they possess two different alleles, their genotype is classed as heterozygous for that locus. Alleles of the same gene are either autosomal dominant or recessive. Is AA genotype heterozygous? Individuals withRead More →
Someone with blood type O has neither the A nor the B allele. The genotype must be OO. What are the 3 types of genotypes? There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). What are the blood genotypes? There are four hemoglobin genotypesRead More →
