Remember, a chromosome carries genes in linear order; a gene is a segment of code that dictates what trait will develop; and alleles are forms of a gene. For an organism to beheterozygous, it has to have a different allele for the same gene at the same point in the chromosome. Let’s...
What is the phenotype of a homozygous dominant organism? What are Mendelian phenotypic inheritance patterns? What principle is when two alleles on different chromosomes can be inherited in any combination? Which pairs of alleles that both affect the phenotype when present in the heterozygous state?
What are genes, chromosomes, and alleles? What are the potential offspring from a mating between two heterozygous individuals? What type of allele is always expressed regardless of whether the individual is homozygous or heterozygous for it? A. Both the dominant and...
A classic example of dominance isthe inheritance of seed shape (pea shape) in peas. Peas may be round (associated with allele R) or wrinkled (associated with allele r). In this case, three combinations of alleles (genotypes) are possible: RR and rr are homozygous and Rr is heterozygous....
Each genetic trait can be located at a particular site or locus on a chromosome, and in a pair of homologous chromosomes, there will be two copies of the alleles which code for a particular trait. In homozygous animals, these alleles are identical. Heterozygous animals have two different allel...
i have a problem distinguishing who's the father of my upcoming baby girl. I'm eight months pregnant. way back then, i broke up with my boyfriend and had a new one in the same month. we had sex, but in the same month as well, my former boyfriend and i were reunited and we also...
Heterozygotes and Homozygotes If an individual inherits two of the same allele, they are homozygous for that gene. If they inherit two different alleles of the gene–one from their father and the other from their mother–they are heterozygous for that gene. If they inherit only one allele of...
Genotypic Ratio = 1:2:1 (1 Homozygous Purple, 2 Heterozygous Purple, and 1 Homozygous White flower) iii)Law of dominance:This is also called Mendel’s first law of inheritance. According to the law of dominance, hybrid offspring will only inherit the dominant trait in the phe...
traits, such as the tobiano pinto pattern and the creme gene. And don't forget sorrel...sorrel horses are homozygous for "non-black," or red. Breeding a sorrel to a sorrel will always produce a sorrel. But you can'tvisuallytell the homo/heterozygous states for dun, roan, black, or ...
A recessive trait is one that is only expressed when an organism has two recessive alleles for that trait. They are less common than dominant traits in most populations because dominant traits will appear in those with both homozygous dominant and heterozygous alleles. What are examples of recessiv...
