Answer:
Probability is the likelihood or chance of an event occurring. Probability = the number of ways of achieving success. the total number of possible outcomes.
Explanation:
Answer:
AaBb
Explanation:
In the given dihybrid cross, the genotype of one parent plant is AABB and that of the other parent plant is aabb. The parent plant with the "AABB" genotype would form all the gametes having "AB" alleles. The parent plant with "aabb" genotype would form all the gametes having "ab" alleles. The random fusion of the gametes from the two parents would produce all the progeny of F1 having the genotype "AaBb".
Therefore, the F1 generation would be heterozygous dominant for both the genes under study.
Cross: AABB x aabb= AaBb
Answer:
answer to what no attachment
Explanation:
Answer:
The correct option is C.
Explanation:
Evolution refers to the gradual development of living organisms from earlier forms to the forms that exist today. One of the principal factors that lead to evolution is the ability of an organism to adapt to adverse changes in its environment. Organisms that are able to survive adverse changes in their environments usually go on to produce offspring that possess their parents' ability to survive. A good example of this is given in option C, where individuals with denser fur were able to survive from severe cold and then give birth to young ones that inherit their parents' ability to survive severe cold.
A true-breeding specimen seems to be homozygous, thus, the blue color flowers must exhibit the genotype BB and the yellow ones must have possessed the genotype YY.
In the given case, when one crosses a flower with genotype BB and other with genotype YY, all the offspring will be BY. As in the next generation, all the flowers appear blue, thus, the blue allele must be dominant.
