If both parent plants are white-flowered, then all of the 1000 offspring would be expected to have white flowers. This is because the white flower trait is a result of a homozygous genotype, and both parents would pass on the white flower allele to their offspring.

If 75 offspring have a Dominant gene, then the parents must have at least one Dominant gene each. This would make them either Dominant Homozygous (DD) or Heterozygous (Dd) for the Dominant trait.
Offspring must inherit traits from its parents because it parents contained genes that were dominant and survived. the genes passed from parent to offspring are important because they are the dominant genes of survival. they passed of survival genes to help their offspring live longer.
An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
Don't give us the options then!! If one parent had 2 dominant genes then all offspring would have dominant phenotype, the same goes for both parents having dominant genes.
No, the offspring of identical parents would not always look like the parents because everyone has dominant and recessive traits, where the recessive traits do not show but is still in DNA. That said, recessive traits not shown in parents can be passed on as dominant traits to offspring - making offspring not always identical to its parents. (this is also called genetic variation)
No, the offspring of parents who are both homozygous dominant for normal red blood cells are not in danger of developing sickle cell anemia. Since both parents carry only the dominant allele for normal red blood cells, all their offspring will also inherit this dominant trait, resulting in no potential for the recessive sickle cell allele to be expressed. Thus, the children will be homozygous dominant as well.
for what animal. it all depends on the dominant gene (allele) and recessive. the genotype of the parents needs to be set up in a Punnett square and with that data you can determine the probability that an animal will have brown fur
