What is a phenotypic ratio?

A ratio that shows the different outcomes you can get from a genetic cross.A ratio that shows the varied outcomes that results from a genetic cross and is based on physical appearance alone. For example yellow flowers, round seeds, brown hair, green eyes etc.The genetic make up of an organism is called genotype and the external appearance or expression of the genetic make up is called phenotype (Color, height, shape etc.). The ratio indicates the number of heterozygotes and homozygotes with reference to the genotypic ratio and to the number of phenotypes expressed as phenotypic ratio. The concept was given by Sir Gregor Johann Mendel, Father of Genetics who worked on pea plant with reference to 7 different characters. The result obtained for a cross between a single character is called monohybrid cross and the ratio is referred to as monohybrid ratio which is 1:2:1 for genotypic ratio and 3:1 for phenotypic ratio.in the dihybrid cross for the phenotypic ratio it is 9:3:3:1.


How many different combinations of the five traits are possible?

There are 2^5 = 32 different combinations of the five traits possible.


If two heterozygous plants create four offspring how many do you predict would be tall?

Using a Punnett square, we can predict that 3 out of the 4 offspring will be tall if both parent plants are heterozygous for the tall trait (Tt x Tt). This is based on the 3:1 phenotypic ratio expected from a monohybrid cross.


Are many undesirable traits in humans recessive?

the term recessive traits referrs to genetics there are no bad traits recessive traits are the ones that are less likely to show up such as lleft handedness dominate traits are things like eye color,the color of your hair and skin etc


Does one gene control many traits or do many genes control one trait?

The answer is simple, genes are inherited and traits are your own uniqueness, genes will have an influence on your traits, so if you are a loud person, that will be one of your traits, and if a parent is a loud person, you will have most likely inherited that gene from them, so the answer is one gene controls many traits because the gene was there first

How many alleles are involved mono hybrid cross?

A monohybrid cross involves just one gene. A dihybrid cross involves two. In a monohybrid cross, there are four possible allele combinations (although depending on the alleles of the parents there may only be one or two possibilities).

How many gametes are formed in f1 generation of trihybrid cross?

In a trihybrid cross, which involves three traits, each parent forms 8 different gametes due to independent assortment of alleles during meiosis. Therefore, in the F1 generation of a trihybrid cross, 64 different genotypic combinations are possible (8 x 8).
