The characteristic always shows in the organism's phenotype. The dominant trait masks the recessive trait. "Weaker" When there is no dominant allele present the recessive trait is shown in the phenotype.
"Weaker" When there is no dominant allele present the recessive trait is shown in the phenotype. Having two identical alleles on a gene which are dominant for the trait. Having two different alleles one is dominant and the other is recessive (Bb). The dominant trait is shown in the phenotype.
Also known as heterozygous (Bb). An organism that has two different alleles for a given trait. A cross between two purebred generations or hybrid and purebred generations.
Explanation: A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous. If that have Aa, they are heterozyous.
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles).
Answer and Explanation: The correct answer: Among the following genotypes the heterozygous genotypes are: 3. Aa and 4.
A heterozygous genotype is a genotype that has multiple different alleles present in that gene. For example, a genotype that is "Tt" would be heterozygous, where the capital "T" could represent the trait of "tall" and the lowercase "t" could represent the trait of short.
Organisms that have two different alleles for a gene are called heterozygous (Gg).
Humans have two sets of chromosomes. Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.
Listen to pronunciation. (HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous. Keep in mind that an organism can't simply be 'homozygous,' period.
The only genotype that is considered to be homozygous at two gene loci is c. rrYY. The first loci is rr which is homozygous recessive, while the second loci is YY, which is a homozygous dominant genotype.
If the genotype of the unknown plant is homozygous dominant (PP), all of the offspring will be heterozygous (Pp) and have purple petals....Heterozygous Genotypic Ratios.PppPppp1 more row•Feb 25, 2020
Examples of homozygous and heterozygous used in a sentence If you have two copies of the allele for blonde hair, you are homozygous for that trait. Having one copy of the allele for blonde hair and one copy of the allele for brown hair makes you heterozygous for hair color.
An example of a homozygous recessive genotype would be tt, where the lower case t's represent the recessive trait. Homozygous means the same and genotype means the gene type.
