Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds
bazaltina [42]

Answer:

(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1

Explanation:

a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".  

b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:

Genotype ratio= 1 GG: 2 Gg: 1 gg

Phenotype ratio= 3 Gray: 1 white

are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location
tatyana61 [14]

Answer:

This definition suits that of "HOMOLOGOUS CHROMOSOMES"

Explanation:

Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.

Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.

Can you see radio waves? How does their position on the electromagnetic spectrum demonstrate this?
MrRa [10]

Explanation:

no, we can not see radio waves. radio waves have the longest wavelength out of all the waves on the electromagnetic spectrum. we can only see visible light, which is towards the middle of the spectrum. the waves below or above visible light on the spectrum have wavelengths that are too long or short for the human eye to detect.
