What term describes the parents in monohybrid cross?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
What do you call an organism that possesses two dominant or two recessive genes fir a single trait?
I think you are referring to the term homozygous. This term applies not to the entire organism but is typically used with regard to one trait. For example, homozygous tall or homozygous dwarf when referring to height in peas. The term heterozygous refers to having one dominant and one recessive gene, or at least to having two different forms of the gene.
What is an individual called that has two different alleles for a trait?
Someone who possesses both a dominant and a recessive form of a gene. So if mum has blue eyes (say it's recessive and expressed as "bb") and dad has brown eyes (say it's dominant and he's homozygous dominant: BB), then all of their children would have heterozygous brown eyes (Bb).
What do homozomes and heterozygous mean?
In genetics, you have certain traits that give you certain features. You get one part from each parent. You may have a dad with brown eyes and a mom with blue. Your dad maybe BB or Bb, and your mom bb. Like in eye color, there's brown, blue, hazel, and other colored eyes. Brown eyes is a dominant trait. So it is homozygous dominant or heterozygous (homozygous dominant = BB, heterozygous = Bb). Blue eyes are a recessive trait (homozygous recessive = bb). So, homozygous are carrying one single part of the trait, and heterozygous is carring a part of both traits.
Having non identical alleles are called?
having non identical alleles r called dne mix ups. i hope this helped u!! good luck!
What does dihybrid heterozygous mean?
"Heterozygous" means having one copy each of the dominant and the recessive allele governing a particular trait."Dihybrid" means that you are following the inheritance of two traits ("di-" = 2).For example: in the peas that Mendel studied, round seeds (allele R) are dominant over wrinkled (r). So a heterozygous plant has the genotype Rr. Yellow seeds (Y) are dominant over green (y). In experiments following these two traits (seed shape and seed color) a dihybrid heterozygous individual therefore has the genotype RrYy.A dihybrid cross involves observation of two traits, e.g.RRYY x rryywhich would yield an F1 entirely made up of RrYy individuals.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
What is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes?
Attached earlobes are a recessive trait. When one parent has attached earlobes and the other is heterozygous for free earlobes, the chances of any particular offspring having attached earlobes is fifty percent.
What term describes the parents in a mono-hybrid cross?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
In humans straight toes S is dominant over curled toes s What would be the result of a cross between a recessive male and a heterozygous female?
The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).

Will an offspring show a recessive trait if only one of its parent has the gene for that trait?
A family tree is a great idea, but the science is based on probability. The probability that a recessive trait will show up in a family is 25% if both parents are carriers. In order for a recessive trait to show up in a person, he/she must inherit a copy of the recessive trait from both parents. If one parent is recessive, let's say "rr" and the other parent is a carrier, say "Rr", the probability is 50%. If both parents are recessive, the probability is 100% (rr x rr). If neither parent carries the trait the probability is 0% (RR x RR). BUT, this only tells you what MIGHT happen. We all know that the probability of having a boy is 50:50, but we all know families of all boys. So it would be interesting to see if the probability works out in your family. If you do a search on the web for "genetics" or "probability and genetics" you will get plenty of hits. vanhoeck

How do you deterime phenotypes?
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
