A man who is heterozygous for type B blood mates with a woman with type O blood. The baby has type B blood. What is the baby's genotype? Ans-- BO - The baby must have at least one B allele to have type B blood. A pea plant that is heterozygous for the purple flower color has genotype Bb. According to the law of segregation, the gametes from this plant would have what genotypes? Ans-- B and b - During meiosis, half of the gametes will get the B allele and the other half would get the ...

*** Take a look at the attached picture and take note of the differences and similarities between animal and plant cells. Ans-- Animal cells do not have a cell wall or chloroplasts. While vacuoles can be found in animal cells, they are not as large those found in some plant cells - Vacuoles in plants are where large amounts of water are stored for use by the cell. The vacuole provides physical support for the plant cell. - All cells have a cell membrane. Some, like plant cells, just have a...
