What else can I help you with?
What characteristic determines whether organisms belong to the same species?
The number of chromosomes. For example, humans have 46.
What does codominonce mean in geneticists?
Codominance is a condition where heterozyous alleles at the same site produce and intermediate result. Ex. Red flowered plant crossed with White flowered plant yields 100% Pink flowered offspring. Ex. White Shorthorn cow crossed with Red Shorthorn yields 100% roan offspring.
How many does it reproduce?
Generally, an organism reproduces to produce offspring that can inherit its traits and continue its lineage. The number of offspring produced can vary significantly between different species and reproductive strategies. Some organisms produce many offspring with low chances of survival, while others produce fewer offspring with higher chances of survival.
Two dissimilar individuals are crossed in the process of?
When two dissimilar individuals are crossed in a process, it can lead to genetic variation and potentially produce offspring with a combination of traits from each parent. This can lead to increased diversity within a population, which can be beneficial for adaptation and survival in changing environments.
Purebread tall plants are crossed with what plants?
Purebred tall plants can be crossed with purebred short plants to produce hybrid offspring with intermediate heights. This type of cross is an example of an incomplete dominance inheritance pattern where the traits from both parent plants are partially expressed in the offspring.
What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
What must true for two organisms to be considered the same species?
they can produce fertile offspring
Do organisms have to be the the same species in order to breed and produce offspring?
No, organisms of different species can breed and produce offspring. Donkeys and horses can breed and produce mules but mules cannot produce offspring.
Can a cow mate with a cat?
No, cows and cats are different species and cannot successfully mate and produce offspring. Their genetic makeup is too different for them to produce viable offspring.
Why was it important to Mendel's work that peas were true-breeding?
because it helped Mendel discover which plants would be crossed to produce offspring.
Individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring will all inherit one copy of the dominant allele (from the heterozygous parent) and one copy of the recessive allele (from the homozygous recessive parent). This results in all offspring being heterozygous for the trait.
Can bobcats mate with domestic cats and produce viable offspring"?
No, bobcats and domestic cats cannot mate and produce viable offspring because they are different species with different numbers of chromosomes.
Can a cat and human breed?
They are different species. Feline and a canine animals can not mate, and produce offspring.
A researcher studying inheritance found that when black mice were crossed with white mice all the offspring produce were gray. What is this an example of?
This is an example of incomplete dominance.
Can bobcats mate with house cats and produce viable offspring?
No, bobcats and house cats cannot mate and produce viable offspring because they are different species.
Can a rooster mate with a guinea hen to produce offspring?
No, a rooster cannot mate with a guinea hen to produce offspring because they are different species and cannot interbreed.
Can a moose and a cow produce offspring?
No, they cannot because their chromosomes are different.
