How would you represent the alleles of a plant that is heterozygous for seed color?

The allele for yellow peas is dominant to the allele for green peas. How could you represent the alleles of a plant that is heterozygous for seed color. I would represent the alleles of a plant that is heterozygous for seed color by using Yy. The allele for purple flowers is dominant to the allele for white flowers.

Which describes an organism that has nonidentical alleles for seed color?

heterozygous

Which of the following is a phenotype for pea plant heterozygous flower color?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

How are dominant alleles often represented?

The different versions of a gene are known as alleles. Genes are often represented by letter symbols. Dominant alleles are represented in an uppercase letter, and Recessive alleles are represented in lower case letters. An organism with two dominant or two recessive allele is said to be homozygous for that gene.

Can alleles be on different chromosomes?

An allele is one of two, or more, versions of the same gene at the same place on a chromosome. It can also refer to different sequence variations for several-hundred base-pair or more region of the genome that codes for a protein. Alleles can come in different extremes of size.

How genes are arranged on a chromosome?

Chromosomes and genes. Genes are arranged linearly along the length of each chromosome (like beads on a string), with each gene having its own unique position or locus. In a pair of chromosomes, one chromosome is always inherited from the mother and one from the father.

What is the difference between alleles and homologous chromosomes?

Two Versions of Each Gene Having two copies of each chromosome, called homologous chromosomes, helps increase both the variety and stability of a species. While each homologous chromosome carries the same genes, they can carry different versions of the gene. Different versions of a gene are called alleles.
