Answer:
RrYy (F1 generation)
Explanation:
This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.
According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.
Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.
In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.
Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
Answer:
The influenza H1N1 virus is transmitted through saliva droplets and mucus from sick people, who by sneezing or coughing without covering their mouth and nose adequately, leave the virus in the air or on their hands, infecting then the objects they touch. As a rare occurrence, a person can become infected with the flu by touching a surface or object contaminated with the influenza virus and then touching the mouth, nose, or eyes.
Pigs sometimes transmit influenza H1N1 virus to people, primarily pig farmers and veterinarians.
