Can alleles be homozygous?

If the alleles are identical, you’re homozygous for that specific gene. For instance, it could mean you have two alleles for the gene that causes brown eyes. Some alleles are dominant, while others are recessive. The dominant allele is expressed more strongly, so it masks the recessive allele.

Can alleles be heterozygous?

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

Which alleles are considered homozygous?

Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

How can you tell the difference between heterozygous and homozygous?

The difference between these traits is:

  1. Homozygous traits have two copies of the same allele.
  2. Heterozygous traits have one dominant allele and one recessive allele.

What is a heterozygous and homozygous?

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.

Does genome include RNA?

A genome is the complete set of DNA (or RNA in RNA viruses) of an organism. It is sufficient to build and maintain that organism. … The genome includes both coding regions (genes) and non-coding DNA, probably present in the nucleus, mitochondrion, chloroplast (for plants), and cytoplasm.

What type of allele is RR?

The heterozygous genotype (Rr) has the dominant round seed shape as its recessive allele (r) is masked in the phenotype.

What are the differences between genes and alleles between homozygous and heterozygous conditions?

Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents.
