Answer:
D) A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied.
Explanation:
When we do a monohybrid cross, we look at one characteristic at a time. When you do dihybrid cross, you are looking at characteristics.
Monohybrid cross example:
If black fur (B) is dominant over white fur (b) what is the probability of black fur in an offspring between two dogs heterozygous for the trait?
Bb x Bb
B b
B BB Bb
b Bb bb
So the probability of black fur is 75%.
Dihybrid example:
If black fur (B) is dominant over white fur (b) and short hair (S) is dominant over long hair (s) what is the probability of white fur and long hair in an offspring between two dogs heterozygous for both traits?
BbSs x BbSs
BS bS Bs bs
BS BBSS BbSS BBSs BbSs
bS BbSS bbSS BbSs bbSs
Bs BBSs BbSs BBss Bbss
bs BbSs bbSs Bbss bbss
The answer would be 1:16 = 6.25%
The terms monohybrid cross and dihybrid cross refer to A dihybrid cross involves organisms that are heterozygous for two characters being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied.
To understand what a dihybrid cross is, we define it as a cross in which two characters are compared simultaneously, for example, plant height and flower color in pea plants, in order to determine how much is transmitted to the offspring.
A hybrid whose parents differ only in hereditary character. Usage example of the word Monohybrid: The monohybrid cross is different from the dihybrid cross.
With these information, we can conclude that terms monohybrid cross and dihybrid cross refer to A dihybrid cross involves organisms that are heterozygous for two characters being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied.
