Recessive alleles are masked by dominant alleles. A person's genotype is the combination of the alleles they have. If a person inherits two dominant alleles, they are said to be homozygous dominant. If a person inherits two recessive alleles, they are said to be homozygous recessive. If a ...
Allele pairs are described using the terms heterozygous and homozygous. Every diploid entity comprises two copies of each of the genes, wherein each could be recessive or dominant. Dominant alleles are expressed to give rise to a phenotype, whereas the recessive alleles remain unexpressed. Both the...
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...
The autosomal recessive gene tra transforms a female mosquito into a phenotypic male when it occurs in the homozygous condition; these transformed females are sterile. The tra gene has no effect on XY males. Determine the F1and F2 generations from the c...
When a parent who is heterozygous for a trait is crossed with a parent who is heterozygous for a trait, the offspring will (remember homozygous means two of the same alleles and heterozygous means two different alleles) What is the genotype of a cross between homozygous dominant and homozygous...
Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. Individuals homozygous for such defective alleles lack a normal metabolicfunction, and this loss of function leads to the disease state. Clearly there ...
The traditional North American sweet maize is homozygous for a recessive sugaryl (sul) allele. Determining the number of unique alleles among sul maize races is relevant to the debate in archeology and evolutionary biology over whether independent mutation or migration plays a dominant role in the ...
- Options with homozygous conditions (e.g., AA or BB): These do not represent codominance because they express only one trait. 4. Conclusion: Based on the understanding of codominance and the evaluation of the examples, the correct answer would be the option that includes either HBA/HBS (si...
It is unknown why birds developed the ZZ/ZW genetic sex determination system, where males have homozygous sex chromosomes (ZZ), and females have heterozygous (ZY) sex chromosomes. However, it is possible that male sex characteristics that increased the likelihood of mating but decreased the likelih...
Give an example of each type of inheritance. When two alleles of the same gene are different, the individual carrying those alleles is said to be ___. (a) recessive (b) heterozygous (c) phenotypic (d) somatic (e) homozygous. Alleles are: a. recessive traits b. dominan...
