When an organism is heterozygous for a trait, the resulting phenotype for that trait expresses only the dominant allele . 当一个有机体的一种特性是杂合的,这种特性产生的表现型就只表达显性等位基因额特性。 blog.sina.com.cn 2. Furthermore, the gene has no negative effects on agronomic traits no...
For example, a pea plant might have the alleles for round seeds "RR" (homozygous) instead of "Rr" (heterozygous) which would be alleles for both round and wrinkled seeds. Is AA homozygous or heterozygous? "AA" is homozygous because both the alleles are the same. "Homo" typically means ...
each genomic location gets these two different forms of a gene called alleles. Each allele of a gene influences the genetic makeup and expression for that gene. There are two different alleles – important to classifying homozygous and heterozygous traits: dominant alleles (usually denoted with a ...
Inheriting an identical version (allele) of a gene from both of your parents makes you homozygous for that gene. Homozygous traits, such as blue eyes or red hair happen when normal genes are passed down. If you inherit mutated alleles, it can lead to homozygous genetic diseases. ...
Humans can beheterozygousfor traits as well. To oversimplify it, you might inherit one copy of the “get freckles” allele and one copy of the “don’t get freckles” allele, meaning you may or may not get freckles as a result.
In a dihybrid cross between an organism heterozygous for both traits and another organism heterozygous for both traits, how many of the offspring would be homozygous dominant? How many of the offspring would be homozygous recessive? Blood type is a multiple allelic ...
What would the genotype and phenotype be of the possible offspring of two parents who were both heterozygous for sickle cell allele? Use a punnet square to show this. For your symbols, please use A to In co-dominant traits, what is t...
sets ofhomologous chromosomes, which are paired chromosomes that have the same genes at the same positions along each chromosome pair. Although homologous chromosomes have the same genes, they may have different alleles for those genes. Alleles determine how particular traits are expressed or observed...
