a. would have the same phenotype

The genotypes of both plants are different. One plant has a dominant and a recessive allele (Tt) while another plant has two dominant alleles. However, as both plants have dominant alleles (T), these alleles will be expressed in both plants resulting in the formation of similar phenotypes. As a result, both plants will have the same phenotypes determined by dominant allele T.

What are the phenotype and genotype ratios for a mix between homozygous dominant flower with red (R) pedals and a homozygous recessive flower with white (r) pedals?

RR x rrF1: 100% RrIf complete dominance than phenotype will be 100% red flowersIf incomplete dominance – 100% pink flowers

In humans, if P represents the dominant allele for extra fingers and toes (polydactyly) and p is the recessive 5-fingered allele, which of these genotypes would indicate a person with five fingers?

A person with five fingers will be homozygous recessive and he can have only one genotype possible- pp.PP and Pp genotype would indicate polydactyly.

If you cross a homozygous dominant almond shape eyes with homozygous recessive round shape eyes, what is the probability that the offspring will have phenotype of almond shape eyes?

Almond shape eyes - dominant trait, let it be Rround shape eyes - recessive trait, so it will be rThe cross : RR * rrOffspring: Rr (so the phenotype -...

In humans, diabetes is a sex-linked recessive trait. If a homozygous normal woman and a man, whose mother is a diabetic, have children, what will be the phenotypes and genotypes of their children?

If woman is normal homozygous, she has genotype XD XD. If mother of her husband is diabetic, he has genotype XdY and also is diabetic.So if they have children, they...

In rabbits straight ears are dominant to floppy ears. Black eyes are dominant to red eyes. Two rabbits are crossed. SSBB x ssbb what are the parents phenotypes

Phenotype: It is the observable trait in an individual because of the genetic makeup for that trait. Like here, the phenotype i.e. the observable trait in the rabbit are floppy...

In squash plants, yellow fruit (Y) is dominant to white fruit (y). If two plants heterozygous for yellow fruit are crossed, what are the possible genotypes of the offspring?

For this to be possible, one parent would have to be homozygous dominant and the other would have to be homozygous recessive.
