Red color being governed by a dominant gene, all offsprings from this cross will have red flowers.

What is the result of two recessive alleles joined?
Two recessive alleles (homozygous) will result in the recessive trait being expressed as a phenotype.
What is a F1 cross?
F1 cross is the crossing that takes place at the first filial generation before the second filial generation.In this crossing,two homozygous parents are crossed together to get one homozygous offspring and three heterozygous offspring which will give a phenotypic ratio of 3:1. First filial generation is also the phase where the production/crossing started.I hope i av been able to answer your question to my own knowledge as a baby microbiologist
The offspring of two parents that are heterozygous for a given trait have a percent chance of being homozygous for that trait?
This would result in 1 heterozygous offspring. You can think of it like this: If the first parent is homozygous it would have AA alleles, the second heterozygous parent would be AB. When they mix genetically it would result in 4 combinations: AA, AA, AA, AB. As there is only one B there can only be one heterozygous offspring. This is not expected it is certain.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
What crosses will result in dominant phenotype offspring?
Don't give us the options then!! If one parent had 2 dominant genes then all offspring would have dominant phenotype, the same goes for both parents having dominant genes.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
Assuming there is no co-dominance or partial dominance, the result would be that 100% of the offspring would be blue, heterozygous flowers with the phenotype Bb.
Why does the cross between two parents that are homozygous for contrasting traits result in offspring that are heterozygous?
They R pretty wierd!
What happens to the alleles between the P generation and the F2 generation?
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
What happens to alleles between the p generation and F2 generation?
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
The first filial generation is the result of?
The first filial generation is the result from a cross between parents homozygous for different alleles at a locus. This is when where an individual inherits the same alleles for a particular gene from both parents.
What is the result of two recessive alleles joined?
Two recessive alleles (homozygous) will result in the recessive trait being expressed as a phenotype.

What offspring would you get if you cross a homozygous tall plant with a homozygous short plant?
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE

When they mix genetically it would result in 4 combinations: AA, AA, AA, AB. As there is only one B there can only be one heterozygous offspring. This is not expected it is certain.
Why are lots of flowers brightly coloured?
To attract insects and encourage pollination to result in more flowers growing.
Does inbreeding result in offspring that are heterozygous for most traits?
Inbreeding results in offspring that are homozygous for most traits - the variability tends to be bred out of the population.
What is the difference between a manipulated variable and measured variable?
The manipulated variable is the variable which researches change, while the measured variable is the variable that changes as a result of the manipulated variable. Consider this simplified question: Do flowers grow better with more water? Researchers plant flowers and put 10mL in one pot, 20mL in another, and 30mL in another. This is the manipulated variable. Researchers measure how tall the flowers are. The height of the flowers is the measured variable, because it changes as a result of the amount of water added.
