How do you know if a genotype is heterozygous or homozygous?
Because an organism has two sets of chromosomes, it usually only has two options to choose from when determining phenotype. If an organism has identical genes on both chromosomes, it is said to be homozygous. If the organism has two different alleles of the gene it is said to be heterozygous.
Is CC a heterozygous or homozygous?
The observation that the agouti parent of unknown genotype can have an offspring with the albino phenotype (cc) means that the parent must be able to transmit the recessive c allele. Thus the parent is heterozygous (Cc) at the C locus.
What’s the difference between homozygous and heterozygosus chromosomes?
Homozygous will have the same colour alleles on homologous pairs, i.e. ‘RR’ or ‘rr’ and the heterozygous will have different alleles on homologous pair of chromosomes, i.e., Rr. In this article, let us discuss the difference between homozygous and heterozygous.
Can a heterozygous dominant genotype produce blue eyes?
The heterozygous genotype and the homozygous dominant genotype both will produce brown eyes, though only the heterozygous genotype can pass on the gene for blue eyes. The homozygous dominant, homozygous recessive, and heterozygous genotypes only account for some genes and some traits.
What is the difference between hemimeans and heterozygous?
Heterozygousmeans that the two alleles are notthe same. Thus, genotypes such as Bb, or B1B2 are homozygous. Hemizygous. Hemimeans “half”. The term hemizygousis actually an oxymoron. It literally means “half-yoked”. More technically, hemizygous means that there is only one allele (instead of two) in a diploid cell.
What’s the difference between an RR and a homozygous allele?
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 heterozygous.
