Answer:
Box 1: AA
Box 2: Aa
Box 3: AA
Explanation:
In order to figure out the pedigree, you first have to do a punnet square- kind of like cross-multiplying. EX: For the first box: Aa x AA
For box one, we know that it is Aa, and not AA, because box 2 has to be AA.
We know that because Aa X Aa would give us some "aa" offspring which we do not see in the last generation (see 2nd pic). The only way to get no "aa" offspring is to have an AA X Aa cross.
Weathering can be caused by rain,snow,heat,and as well as wind.
Answer:
b. allele
Explanation:
An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).
<u>The other options are wrong because:</u>
The genotype is the combination of alleles an individual has.
The karyotype is an individual's collection of chromosomes, paired and ordered.
A homozygote individual has the same alleles for a particular gene.
A heterozygote individual has different alleles for a particular gene.
No, because the immune system is already battling with the virus or disease
