Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
What else can I help you with?
When an individual have two identical alleles for the same trait it is called?
Having two similar alleles for a trait is called being homozygous. It is possible to be homozygous for a dominant or recessive trait.
What is similar because the heterozygous phenotype is different from the homozygous dominant phenotype?
Both heterozygous and homozygous dominant genotypes have the same dominant allele, resulting in a similar overall phenotype. The difference lies in the fact that heterozygous individuals have one dominant and one recessive allele, leading to a different genotype than homozygous dominant individuals who have two dominant alleles.
Is it true that in co dominance neither of the alleles is dominant or recessive?
True - in codominance neither allele is dominant or recessive. Codominance results in both alleles being expressed in the phenotype (characteristics of the organism). For example, if R is red and W is white - a flower with the genotype RW would have white petals with red patches (or something similar).
What is the difference between homozygous and heterozygous organism?
if for example we had a yellow and a blue flower yellow being dominant (Y) and blue being recessive (y) a homozygous organism has the phenotype of either being YY or yy and a heterozygous organism could only be Yy.
Is this true or false in codominance the alleles are neither dominant nor recessive?
True - in codominance neither allele is dominant or recessive. Codominance results in both alleles being expressed in the phenotype (characteristics of the organism). For example, if R is red and W is white - a flower with the genotype RW would have white petals with red patches (or something similar).
What is the definition of homogeneous?
Both alleles of one trait are either dominant or recessive. Not one dominant and one recessive. For example, the homogeneous hair of a cat would have both alleles of that trait be the same, say, BB or bb. NOT Bb.The above definition applies in the field of genetics. More generally, the word means "Of the same or similar nature or kind".
Homologous chromosomes are similar in all of these characteristics EXCEPT?
Homologous chromosomes are similar in terms of size, shape, and genes, but they are not similar in terms of the specific alleles they carry. Each homologous chromosome may carry different alleles for the same gene, leading to genetic diversity.
Can you explain how individuals with the same alleles for a specific trait are similar or different from those with different alleles for the same trait?
Individuals with the same alleles for a specific trait will have similar physical characteristics related to that trait. On the other hand, individuals with different alleles for the same trait will have varying physical characteristics. This is because alleles determine the expression of traits, and different alleles can lead to different outcomes in terms of physical appearance or other characteristics.
How is co dominance and incomplete dominance similar?
Both co-dominance and incomplete dominance involve a situation where alleles do not follow the traditional dominant-recessive pattern of inheritance. In both cases, heterozygous individuals show a phenotype that is a blend of the two homozygous phenotypes. The main difference is that in co-dominance, both alleles are fully expressed, while in incomplete dominance, the phenotype is a mix of the two alleles.
When an organism has two identical alleles for a trait it is said to be what?
In genetics, two similar alleles for a trait is known as homozygous. Two alleles that differ from one another is known as heterozygous.
Which form of selective breeding crosses parents with the or similar set of alleles?
Inbreeding
How is inheritance be multiple alleles and poly genic inheritance similar?
Multiple alleles is when there are more than 2 alleles in a single trait. In blood type, instead of either one dominant and one recessive type alleles, there is one recessive allele (type O) but two dominant alleles(type A and B). Polygenic inheritance is when more than one gene controls a single trait, such as height in which three genes are responsible.
