Answer:
A. 1/16
Explanation:
If we break the dihybrid cross of AaBb X AaBb into individual monohybrid crosses:
Aa X Aa :
A a
A AA Aa
a Aa aa
1/4 of the progeny will be homozygous for dominant allele (AA)
Similarly, in cross Bb X Bb 1/4 of the progeny will be homozygous for dominant allele (BB)
Hence, in cross AaBb X AaBb:
1/4 * 1/4 = 1/16 will be homozygous for both the dominant alleles.
The immune system.
The immune system acts as a defense system of the body. It fights against bacteria, viruses and any other disease causing pathogens. Some chemicals can weaken the immune system and make them vulnerable.
A. 50% are pink and 50% are white, if you do the table it shouldn’t be as hard
B. Yes because RW includes the WW from White but it could take a couple offspring to get Red (from my understanding from last year)
Ok, well I can first tell you this proteins are definitely part of structure
