Answer:
meiosis I
Explanation:
Reduction of the number of sets of chromosomes occurs during meiosis I.
During Meiosis I crossing over of genetic material occurs between chromosome pairs
Answer:
The type of symmetry a has is called bilateral symmetry. :)
Answer:
The cross of a heterozygous fly with a homozygous fly can be shown as follows:
r r
R Rr Rr
r rr rr
The results show that there is a 50% probability that the flies produced will have red eyes. Their genotypes will be heterozygous.
The results of the punnet square show that there will be a 50% probability that the offsprings will have brown eyes. Their genotype will be homozygous recessive.
A homozygous trait can be described as a trait which has same alleles for the gene which encodes the trait. Heterozygous means that both the alleles for the trait will be different.
They need to be able to sense incoming threats
